Electric Recumbent Bicycles Hackaday

If you liked our post about bikes and skates with weed whacker engines but want more power and more Challenge, we have good news. We’ve found some great instructions on adding motors to recumbent bicycles, which we’ll take you through after the break.

​

The first project we found is the E-cumbent by [Matt Shumaker] . [Shumaker]’s ongoing project uses a power unit he constructed out of RC airplane electronics: the motor, the controller, a servo tester, and a battery eliminator circuit connected to 14 lithium polymer cells plus several CNC milled parts. The power drive connects to a sprocket mounted on the left side of the rear wheel. The bike is constructed with two reduction stages; the second stage has a freewheel that allows the rider to pedal while the motor idles, use the motor and pedal power combined, or use motor power alone. [Shumaker] also built a display console onto the handlebars, which shows trip information, MPH, and information on battery usage.

[Warren Beauchamp] designed a somewhat more simple electric recumbent he calls the Cuda-E. This design uses a 450 watt motor from a Mongoose pedal/electric motocross bike. It doesn’t just take the motor, though: it uses the entire rear subframe...
