Electric bike regulations in Canada

Every now and then, a Canadian customer asks, "Can I buy a US 750W ebike?" Unfortunately, the answer is "no," and the reason is that Canada regulates that power be limited to 500W and the top speed be limited to 32 km/h. To learn more about provincial regulations, see this site: https://ebikebc.com/electric-bike-regulations-in-canada/. You may ask, "Do I need a license, registration, or insurance?" Again, there are provincial differences, specified on the noted website. Check out your province, be safe, and ride on!

Canadians encouraged to shop early!

While our ebikes are not typically delivered by Canada Post, we are posting this video message from Rod Hart as a general reminder to shop early for this Christmas season. Ebikes make great Christmas gifts, and will give your loved one much anticipation for getting outdoors as soon as spring hits. We are expecting new inventories in mid-November, so get on board and order early.

From Rod Hart (Canada Post):

As COVID-19 continues to pose challenges and Canadians shift their shopping to online, we expect that this will be a holiday season like no other. To manage significant volumes and avoid a holiday capacity crunch, we’re not only scaling up, we’re also asking Canadians to shop early.

Watch this short video – which is featured on canadapost.ca and on social media – from Rod Hart, Chief Customer and Marketing Officer, as he speaks to Canadians about the upcoming holiday season and asks them to break with tradition by shopping earlier: https://www.youtube.com/watch?v=9nZ7GMAuW3c&feature=youtu.be

Thank you, and stay safe.

Canada's Top Growing Business

Canada's Top Growing Business

In 2017, I took the leap to quit my job and start my own business, DJ Bikes. Being the Janitor and CEO of this company, I needed to learn everything on the spot and make good decisions. Today, I am proud to announce that DJ Bikes has been awarded a place on Startup 50: Canada’s Top New Growing Companies 2020 (https://www.canadianbusiness.com/startup-list-2020/). Yes!

I remember the time I sold my first bike. I jumped up and yelled “Someone bought my bike!” I can't believe how fast DJ Bikes has grown! My business is now a multi-million-dollar revenue company and the momentum continues. I have a team who share my passion.

DJ Bikes is a perfect example of the "Canadian Dream.” I am an immigrant from Taiwan who came to Canada at the age of 14. Some people initially doubted my decision to work for myself but now support me. My journey has been nothing short of amazing, and along the way I’ve met many great people who offered me help. There continue to be fears and challenges to overcome, but today, I claim that my dream has come true.

Paulo Coelho has said “When you want something, all the universe conspires in helping you to achieve it.” Really though, it’s all grace, and I have so much to be grateful for.

Announcement About Amazon's Delivery Issue During COVID-19

For the past 4 years, DJ Bikes has been working closely with Amazon. We chose to send all inventories to Amazon's warehouses in both the US and Canada so we can guarantee a fast delivery. Usually, Amazon's delivery is 2 to 5 business days, and the delivery process has been consistent until early this year.

Amazon's now has a new policy. Since the COVID-19 outbreak happened, Amazon has refused to deliver over-sized packages. Because of this, DJ Bikes made a critical but essential decision about its inventory management. In July 2020, we started managing and delivering all bike orders by using our own capacity (warehouses).

You might have experienced that your Amazon order has been indefinitely pending, and that is outside of our control. If it happens, our suggestion is to cancel the order from Amazon, and order the same bike model on this website.

 Your order will be managed and delivered to you by DJ Bikes!

Here is the note from Amazon just for your reference.

Amazon Selling Partner Support

Upon reviewing this case, I understand that your order are unfulfilled through FBA under CA market place. This is the last COVID-19 update we received and this is the only cause why your orders are not being fulfilled.

WHAT?

Amazon is temporarily limiting receiving, restocking, and shipping for products that require two people to pick, pack or ship. This applies to parcels and individual products weighing between 49 lbs - 99 lbs (22.2 Kg - 44.9 Kg).

WHEN?

April 21, 2020 (And still going on)

WHAT IS THE IMPACT FOR YOUR CUSTOMERS?

A mass mail will be sent to the sellers informing them about the change. For products and parcels already on their way to our fulfillment centres and that are between 49 lbs - 99 lbs (22.2 Kg - 44.9 Kg), we will make every effort to receive these products while adhering to guidance from health authorities. Any shipment rejected will be sent back, however we expect these cases will be limited. If Sellers have already created a shipment for products weighing between 49 lbs - 99 lbs (22.2 Kg - 44.9 Kg) and it has not already been shipped, Sellers must cancel the shipment.

Electric Bikes Motor Types: Mid Drive VS Rear Hub

By Daniel Yang
on June 27, 2020

Introduction

Motors are an important component of electric bikes, because they supply energy to the bike by converting electrical energy into mechanical energy. Earlier electric motors used brushes to vary the path of current flowing into the motor. The recurrent action made electric motors less efficient and more prone to deteriorate over time. For more than 10 years now, electric bikes have been using brushless DC motors, and as the name denotes, they do not have brushes in their operation. For brushless DC motors, electric energy is converted into mechanical energy with the use of permanent magnets and electromagnets.

Inside the brushless DC motor, there is the stator, which is the stationary electrical device, and the rotor, which is the rotating electrical device. The stator consists of wires coiled round an assembly of separate electromagnets arrayed in such a system that they form a hollow tube, with the individual electromagnets having one pole facing the direction of the centre of the tube. This is the stationary component of the brushless DC motor. The rotor, on the other hand, consists of an assembly of permanent magnets inside the hollow tube, with the poles facing the direction of the stator poles. The rotor is the rotatory component of the brushless DC motor. All the bikes offered by DJ Bikes have a brushless DC motor.

Operating mechanism

The purpose of this configuration of the motor components is to cause rotatory motion of the motor shaft due to the rotatory movement of the rotor. When the motor controller pulls electric current to the stator’s electromagnets from the battery, they repel and attract the rotor’s electromagnets, thereby causing the rotor to rotate. The stator is connected to a shaft.

There are two major types of motors on electric bikes: mid-drive motor and hub motor. For the mid-drive motor, the shaft rotates to produce torque, and by a small chainring joined to the shaft, power is supplied to the pedals which assists you to pedal the bike. On the other hand, for hub motors, the shaft is the axle, and thus does not rotate. The rotatory action is caused by the rotor, which causes the complete motor to rotate to produce torque, by rotating either the front or rear wheel.

Overview: Types of Motors

There are four types of motors that are used on (or have been used) on electric bikes. They are listed below:

Mid-drive Motors

Mid-drive motors are located in the middle of the frame of the bike, typically positioned at the bottom bracket. The electric motor produces a torque that rotates the shaft (connected to the stator), which is connected to a small chainring. With this type of motor, no extra source of power is needed, as the motor complements the energy you exert on the pedals within the chain drive of the bike. Typically, embedded within the motor pack is a gear reduction technology. To protect the small chainring from fracture when the bike is not in gear, most mid-drive structures comprise of gear sensors which cut off power to the motor. The DJ Mid Drive Fat Bike uses a powerful Bafang rated watt 48V 750W “mid-drive motor.”

Direct-drive Hub Motors

In direct-drive hub motors, the shaft of the motor is the rear axle, in a stationary position, while the motor (i.e. the hub) rotates about the shaft, and thereby creates acceleration. These are the least complicated of all electric bike motors. Typically, direct-drive motors have a larger diameter compared to geared hub motors, which produces increased torque. These motors have the unique ability of moving forward and backward with even efficiency. During the braking process (which includes slowing down or coming to a complete stop), direct-drive electric bikes can also produce electric energy. This process is called regenerative braking. During the braking process, energy flows to the battery from the wheels, instead of being dissipated as heat. This “saved” energy is now used when the bike becomes operational, or increases its speed.

Geared Hub Motors

Geared hub motors are similar in operation to direct-drive hub motors, with the exception of anmelectric motor that rotates within the hub at a considerably higher speed. The hub rotates at the lower speed, due to the shaft of the motor connected to a series of orbital gears that are connected to the hub. This system creates additional torque but lower speeds. Typically, geared hub motors have a smaller diameter than direct-drive motors, because a larger motor is not required to produce the equivalent quantity of torque, however, the orbital gears make the hubs larger. These motors also comprise of a “freewheel”, which removes the possibility of regenerative braking, but will cruise smoothly rather than produce a slight drag when they are not under power. Electric bikes with geared hub motors perform in a similar fashion with conventional bicycles. The majority of the bikes offered by DJ Bikes are Geared Hub Motors.

Friction Motors

Friction-driven motor electric bikes are not as common as the hub and mid-drive systems, however, they have the advantage of a cheaper design for users who want to transform a conventional bike with marginal effort. A bolt-on motor drives a small wheel linked to the tire. The location of this kit is usually below the chainstays, above the seat trays, or attached to the fork’s brake mount. The wheel of the motor rotates the tire, thus causing forward motion. As the name implies, the action of the motor causes increased wear on the tire, however, these kits can be substituted easily between bikes.

Summary

Comparison between Mid-drive motors and Hub Motors

Mid-drive motors: Advantages

  • They perform more efficiently on hills, because the bike can climb at low speeds
  • Due to their centred position on the bike, they offer a more stable ride
  • They are more suitable for electric mountain bikes
  • It is easier to change tires, as there is no wiring between the hub and the frame

Mid-drive motors: Disadvantages

  • An increased wear of the chain due to the addition of the mid-drive motor to the chain leads to frequent replacement of the chains
  • Due to increased mechanical components and a higher gear reduction, it is a more expensive bike

Hub motors: Advantages

  • Due to the fact that hub motors function outside the chain drive of the bike, their chain does not wear out like mid-drive motors
  • They are inexpensive compared to mid-drive motors, because manufacturers are not required to modify the bike’s frame to accommodate a custom motor, and can also be manufactured in large quantities
  • As no mechanical component is used during transmission, they are more reliable and long-lasting
  • They require slight, and in most cases, no maintenance
  • They can still be ridden if the chain is broken, as the hub motor is attached directly to the bike’s wheel and not dependent of the electric bike
  • They are easier to ride

Hub motors: Disadvantages

  • They are heavier compared to mid-drive motors because their motors and batteries are bigger, due to more electric power required
  • It is more difficult to change tires, because you have to remove all the cables associated the hub motor

Comparison between Direct-drive Hub motors and Geared Hub motors

Direct-drive Hub motors: Advantages

  • As a result of regenerative braking, direct-drive hub motors have the advantage of a reduced brake wear
  • Typically, they are more quiet than geared hub motors
  • Compared to geared hub motors, direct-drive hub motors perform better at high speeds

Direct-drive Hub motors: Disadvantages

  • Compared to geared hub motors, they are larger and weigh more, due to additional magnetic material needed to produce a torque of low speed
  • They produce a drag during pedaling

Geared Hub motors: Advantages

  • They are more suitable for low speeds and elevated torque applications
  • With the same torque rating of a direct-drive hub motor, the weight of a gear hub motor is considerably lighter
  • They can cruise smoothly with very little drag
  • They are smaller and less bulky, therefore a preferred choice for commuters

Geared Hub motors: Disadvantages

  • Compared with direct-drive hub motors, geared hub motors experience difficulty in attaining the same speed

Conclusion

What type of motor should you be looking for when buying an electric bike? It really depends on your needs.

History, Development and Classes of Electric Bikes

By Daniel Yang

Development of Electric Bikes

Over the past few years, electric bikes have gained popularity in North America, Europe and Asia, with useage experiencing tremendous growth since 1998. You might therefore be thinking the development of electric bikes started in the 21st century. Research and patents have, however, been documented in the United States since the 19th century.

Ogden Bolton Jr., in 1885, designed a bicycle powered by batteries. This bike had no gears, and with a battery rating of 10V, the motor was able to pull as much as 100A in electric current.

After two years, Hosea W. Libbey, in 1897, developed a bike that was driven by a double electric motor. The motor for this design was inside the hub of the crankset axle.

The development of rear-wheel drive electric bicycles gained popularity just before 1900. In 1898, Mathew J. Steffens designed a driving belt by the outside edge of the wheel, while in 1899, John Schnepf illustrated a back-wheel friction drive electric bicycle with a roller wheel. In 1969, this illustration was reviewed and further developed by G.A Wood Jr, and four fractional motors coupled with a series of gears were included in his design.

In 1992, a bicycle was created named “Zike”, which comprised of a nickel-cadmium battery installed into a frame assembly, in addition to a permanent magnet motor weighing 850 grams (two pounds). Notwithstanding the “Zike”, which was manufactured by Vector Services Limited, there was still a shortage of electric bikes available for sale.

The late 1990s brought about the development of torque sensors and power controls, with Takada Yutky filing for a patent in 1997.

In 1989, the Japanese automotive giant Yamaha assembled an initial model of an electric bike, and further modifications in 1993 with the invention of the pedal assist system.

Classes of Electric Bikes

Today, there are multiple classes of electric bikes. They are generally classified according to the control system and the power that can be delivered from their electric motor. Due to legal problems, there might be different classifications across various countries, cities, towns or provinces, however, electric bikes are generally classified as follows:

  • Pedal Assist System – this is a system where power is supplied by the electric motor to the pedals. Depending on the circumstances, it can be regulated by the bike or user. During pedaling, this system helps to supplement the efforts of the rider

Basic plan of a pedal assist system bicycle, where power is supplied to the pedals by an electric motor

  • Power-on-demand – this is a system where the power supplied to the motor is activated by a throttle. This is installed on all bikes manufactured by DJ Bikes on the handlebar for your convenience, and controlled by the use of your right thumb

Basic plan of a power-on-demand bicycle, where power can be supplied to the motor by a throttle on the handlebar

Electric bikes could have only one characteristic of the above stated classification, or a combination of both. The various sub-categories are listed below:

  • Electric bikes with pedal assist system only – these are either named as “pedelecs”, i.e. bicycles, with a maximum speed and motor power of 25km/hr and 250Watts respectively; or “S-pedelecs”, i.e. mopeds, with a maximum speed and motor power of 45km/hr and 250 Watts respectively
  • Electric bikes with pedal assist system and power-on-demand option – these are the latest models of electric bikes. All the bikes manufactured by DJ Bikes have both of these features. There is the pedal assist that regulates the output power of the motor by turning the pedals; and a thumb throttle which allows you to regulate the power of the motor by the action of your thumb

DJ Mountain Bike Handlebar – the King Meter Display shows you the level of the Pedal Assist System, which can be adjusted by the user, while the throttle helps you regulate the motor power. Other accessories like the display button, bell and shift are shown as well

  • Electric bikes with power-on-demand only – these are bikes where the electric motor is manually activated and engaged by the use of a throttle only, typically on a handlebar. For this bike, the user can use the pedal alone (like a regular bicycle) without the use of the power-on-demand option; or use the throttle to manually supply power to the electric motor to ride the bike; or the rider uses both the throttle, but also supplies energy by physically pedaling the bicycle.

Tips for Battery Maintenance

By Daniel Yang
on June 06, 2020

One of the most important components of your electric bike is the battery. To prolong the life of your battery and ensure the electric bike performs to its optimum efficiency, diligent and purposeful care/maintenance must be done throughout the life span of the electric bike and its battery

Because electric bikes make use of batteries, the user can select the amount of power required. And since the user can determine the amount of power, electric bikes can also be used as a regular bike if no power is selected.

All bikes manufactured by DJ Bikes, have an option of regulating the amount of power from Level 1 to Level 5. The bikes will travel at 20% of the speed limit at Level 1 and 100% of the speed limit at Level 5. If you select Level 0, no power will be supplied to the pedals, therefore at Level 0 the bikes functions like a regular bike.

Electric Bike Samsung Battery 48V 13Ah

All electric bikes manufactured by DJ Bikes come with lithium-ion batteries. They are preferred to other batteries, as they are rechargeable. The other advantages include:

  • Low maintenance, as compared to lead acid batteries, where water levels have to be checked regularly
  • They have a longer lifespan, which reduces the total cost of your electric bike
  • It is easier and faster to charge. The maximum charging period for the batteries provided with all bikes manufactured by DJ Bikes is 6 hours
  • They are lighter in weight when compared to other same sized rechargeable batteries

The question now arises, what can be done to improve the efficiency and longevity of lithium-ion batteries? What are the necessary steps required to get optimum performance of an electric bike battery?

Charging

It is advisable to charge your electric bike’s battery immediately upon assembly of your bike; however, it is also highly recommended you stop charging the battery as soon as the battery is full (100%). If you continue to charge the battery when the maximum battery level has been attained, please note this leads to over-charging at elevated temperatures, and may result in internal lithium metal plating accelerated by a lasting loss in capacity. In layman’s language, it causes irreparable damage to your battery.

Re-charging

It is not advisable to allow the capacity of your battery to drain off completely, i.e. 0%, before recharging (always avoid full discharges). It is highly recommended you recharge your battery, when the battery level is between 20% and 30%. When charging your battery for the first time, it is OK to reach the maximum battery level (100%), however, it is highly recommended you avoid charging to the maximum capacity on subsequent occasions. As far as it is possible, always avoid fast charging or high loads.

At temperatures below 0oC, it is advisable not to charge your battery. This causes metal plating at the battery anode, and can make the battery volatile and dangerous because of the generated heat.

Storage

For an elongated battery life, it is recommended batteries be stored at 40% battery level at a cool temperature. The advisable range of temperature storage is between 5oC or 20oC. This is because lithium-ion batteries do not like high or low temperatures. Temperatures above 20oC decrease the battery life. It is also not advisable to leave the batteries unused for an extended period of time. Therefore, charge at least once every six months to a 50% capacity and store separately from the electric bike. Since 4oC corresponds to the temperature of a refrigerator, you might be tempted to store your battery in a fridge. Never do so, as the humidity can cause rust to the battery parts.

Operating conditions

When operating your electric bike, the advisable range of battery level is between 30% and 80%.

Handling guidelines

  • Do not attempt to dismantle, deform or create holes in the battery
  • Fire or water should not be used to dispose a lithium ion battery. Always check with the local regulatory authorities if you want to dispose or recycle. Do not dump batteries in the local dump or landfills
  • Always keep far from the reach of children
  • Do not touch any leaking fluids on your battery
  • Do not rub your eyes should there be any eye contact with battery fluid. Instead, lift upper and lower lids, and use water to wash eyes carefully and thoroughly for at least 20 minutes, at least until there is no indication of the fluid. Then seek medical help immediately
  • Do not use batteries that have been damaged

In summary, the lithium ion batteries (especially the ones that come with the bikes manufactured by DJ Bikes) are superb, and are designed for longevity. However, its performance and efficiency depend on the maintainability and usage by the user.

All batteries that come with bikes manufactured by DJ Bikes come with a Hazmat Safety (UN38.3) and UL certification, which have passed all quality assurance and control product tests. They are also shipped using the best practices and standards.

Electric Bikes during a pandemic

By Daniel Yang
on May 23, 2020

A few months ago, you probably did not know the term, but “social distancing” is now one of the most commonly used phrases in the world. Medical experts, since March, have stressed the importance of social distancing in slowing the spread of the COVID-19 virus. Cities round the world have been in lockdown, with companies now allowing their employees to work remotely from home. To flatten the curve, medical experts advise we go out only for groceries, medical needs, essential requirements and exercise. The message has been resoundingly clear: we need to keep at least 2 metres (6 feet) from each other.

It’s a good thing that Electric Bikes have not been banned anywhere, and provide a useful, reliable and cost-effective means of transportation. Electric Bikes come in handy for trips to the grocery and drug stores, or other essential needs. While the global pandemic has resulted in a sharp decline of gas pump prices, you still have to pay to put gas in your car. Electric Bikes, in harsh economic times like these, are a cheaper way to travel, especially for short distances. Imagine the savings you will achieve if you can cut down on your gas purchases for your vehicle (and probably pay less for car insurance) if you switch to Electric Bikes? The answer is an affordable (i.e. inexpensive) Electric Bike, like the ones manufactured by DJ Bikes.

 

These are truly tough times for everyone. Governments, organizations, frontline health care workers (who are doing a terrific job by the way!), and you reading this. The truth is, in a global pandemic, everyone feels the brutal impact and it can be devastating. Your body, however, does not need to feel the brunt of the current harsh realities. You need your body to stay healthy, sharp and alert. How can this be done when gyms are shut down? And even when you go out for exercise, you still have to maintain the 6 metres (2 feet) physical distance from everyone else. If you are a fitness enthusiast, and you need to burn calories or maintain your 10,000 steps every day, or if you are glued to your computer screen these days because you work from home and you have that feeling that you surely need to do more exercise, then you might want to consider the array of excellent products DJ Bikes manufactures.

So perhaps you are now considering buying one of those cool Electric Bikes. You are now probably wondering if we can still ship to you. We’ve had some challenges with Amazon deliveries, but the same bikes, with the same selection and service, can be purchased directly from the DJ Bikes' site. Yes, inventory levels have been impacted by the pandemic, but we have not stopped shipping bikes. We too work from the comfort of our homes. This does not affect our efficiency or determination to go above and beyond to satisfy our ever-increasing customer base. Our bikes are easy to assemble, or use a local bike shop (if open) if you need some help. And the DJ Bikes’ team are always available for phone or email coaching.

What is Direct-to-Customer pricing? What about Quality and Service?

What is direct-to-customer pricing?

You will learn that DJ Bikes offers about half the price compared with other electric bikes with similar specifications and performance at local stores or on the internet because we are the only entity between the manufacturer and customers. There is no overhead, distribution layer, retail markup or high price tag. We offer you the direct-to-customer price and empower you to bypass multiple layers of distribution channels to get affordable electric bikes. 

Then how about the quality control and service?

DJ Bikes designs, builds, quality checks, and imports its own bikes and provides full service to its customers to keep its bikes running well. The owners Daniel and Jolin or team of customer service specialists will answer your sales and technical inquiries with full knowledge and passion about the bikes and DJ brand.

DJ Bikes was awarded the title of "Amazon's Choice for Electric Bicycle". There is only ONE electric bike in the Amazon marketplace that can be awarded this designation, based on the received ratings, customer reviews, and price. It is an honor to share it with all our customers.
