[Dave Schneider] Has been chasing the construction of electric bicycles for more than 10 years. When he first started working on it in 2009, the cost was prohibitive. But think about how far we have come in terms of the availability of motors, electronic speed controllers, and battery technology. When reviewing this project this year, He was able to convert a traditional bicycle into an electric bicycle for about $200.
The electric skateboard paved the way for this cracking, because he chose to use the outer rotor motor as the friction drive for the rear wheels. The mounting bracket he made is clamped on the chainstay tube and presses the motor body on the tire.
The speed of the motor is controlled by a rocker switch on the handlebar, but the sensor in the brake lever is the neat part. The magnets added to each brake lever are monitored by Hall-effect sensors, so as long as the rider feels squeeze the front brake (effectively allowing the bicycle to spin freely), the throttle will be cut off, and the rear brake will trigger his built-in system Regenerative braking function!
Of course you can buy these bikes, you can even buy retrofit kits, but it’s hard to exceed $88 [Dave] When the cost of a dedicated motor is usually several times this number, it is spent on the motor. The rest is fairly simple. In addition to ordering batteries and electronic speed controllers, there may be parts you need waiting for you in your parts box.
