Making An Electric Cargo Bike

Worked most of the day adding a motor to my cargo gravel bike. It’s an older Priority Apollo with plenty of life left in it. I did run into some snags.

  • The belt line is way different.
    • I found Walker Brothers in the UK with an adapter for fixed gears.
    • If that doesn’t work I’ll grab a wider wheel my Encore is 33mm wider in the rear.
  • Might have to switch to a flat handlebar.
    • One problem, at a time.
  • Might change sprockets to shorten the belt and reduce the chain angle.
  • Use lock rings as spacers.
