if you have a very early Daum powered Urban Arrow then chances are it may be at the end of its life….i think in principle it would be possible to install an impulse system from a Gazelle or Kalkhoff bike….the battery positioning would be tricky but it may be possible.

Simpler….and arguably more exciting is to convert your Urban Arrow to Bafang BBS motor or similar bbs motor Tongshen, etc. This adapter enables you to do that….comes with the bolts needed to bolt it, simple fit….

mild steel with a black satin powder coat. (the pictures show prototype with spray paint)

this may come as a full kit with motor and battery in the future.

The motor tube is not threaded and will not accept a push fit bottom bracket, BB motor fit only.

main thing you will need that could trip you up is Bafang 1T4 EB-Bus Cable Harness or LCD Display or throttle, brakes,brake sensors,gear sensor Extension Cable for Bafang BBS01B BBS02B BBSHD Mid Motor , the routing from motor to bars via mid mast is tricky, this makes it do-able.. Model: Five PIN cable
