Firstly you need to find the right bicycle type for your physical shape and kind of application (Mountain bike, hybrid, upright, step-thru, cruiser, recumbent, Tandem, Delta trike, recumbent trike, etc.). This should be concluded by you with the help of your health advisors.
Looking at various electric power assist systems we can give you some guidelines. If you are new to the topic the best practice is letting us chose for you. Fill out this form if you are looking for a complete electric bike.
Fill out this form if you are looking for a conversion kit.
You need to provide details such as your weight, expected range, road condition and riding attitude.
Knowing the bicycle frame and style we’d get one step closer to the application and choosing the motor system.
The motor drives the crank independent from the pedals. The power adds up with pedaling and transmitted to the rear cogs through the bike’s chain or belt.
The motor is attached to the frame and the wheels are light.
The best power system for a mountain bike, especially the full suspension bikers who do rock jumping, is mid-drive motor system. Bosch, Shimano STEP, Yamaha, Brose, are the most famous crank motor brands known today. You can only get these motor integrated with an electric bike’s frame and not as a retrofit. The price on these systems is high and they have some performance limitations due to increase reliability and enhanced safety.
There are retrofit able versions of mid-drive motors which can be installed on existing bike bottom bracket. Don’t use such system unless you really want to do mountain biking or concern about the weight of wheel.
Power through transmission always reduces reliability and durability of the e-bike, no matter what quality motor you purchase.
Hub motor system:
Don’t hesitate to go for a hub motor system if you need a reliable commuter or pleasure ebike for city or trails.
The motor is in the center of wheel, whether front or rear. They are lighter, more reliable and durable and best option to go for urban rides.
We have direct hub motors like BionX which is known as a high end Canadian brand for over 10 years. They are smooth, silent powerful and reliable.
Geared hub motors are lighter, more compact and offer higher torque. The light weight and compactness gives the opportunity to mount the motor on front wheel. They are also quite durable and maintenance free. Read this article for more details.
It is a small high speed motor with a rubber pinion which spins the tire by friction such as Add-e motor which went viral for a while.
We don’t think this can be a solid electric bike solution due to the high noise, lack of freewheeling, wearing tire, low efficiency and range and low reliability.
