I previously had a RadCity bike. I eventually got a RadTrike. The ABUS Wheel Lock that RadPowerBikes sells for the RadCity is not compatible with the RadTrike… they have screw holes in the frame for a wheel lock, but they don't sell a wheel lock for the RadTrike.

This adapter is to fit the RadCity Wheel Lock on the front wheel of the RadTrike.

Just snap it right into the frame around the screw hole, then use the M5 screws that came with the lock, to attach the adapter arms to the bike frame. The zip-ties I use in the photos are completely optional and mostly just put there for cosmetics. You can then attach the wheel lock to the adapter arms using your choice of four M5 bolts and lock nuts.

You should print this in a strong temperature resistant material, such as ABS or PETG.

If you appreciate my models, please consider buying me a coffee!
