My bent includes other features including a handlebar-mounted rear-view mirror, bicycle computer, bottle cage, and bright orange colored safety visibility tape installed on the seat rest.
Step 5: The drivetrain
The drivie wheel with 8-speed cassett5 and the derailleur are used up front without modifications. This worked out perfectly. I had to abandon my earlier attempt of using a wheel with a three speed hub because it needed a tension idler complicating the design. Changing gears and braking is done similar to a normal bicycle with shifters and brake levers.
