I got Sue a second battery for her RAD Power Radcity Step-thru 3 (2021). I needed a way to mount it to the bike. I designed and 3D printed a bracket that attaches to the bike rack. It allows the battery to be locked in. It can also act as a wall mount for when you are charging the battery
I put the 3D Print file on:
* prusaprinters.org/prints/69891-rad-power-radcity-ebike-battery-holder-for-rack-or
* thingiverse.com/thing:4894232
parts used:
* Radcity Step-thru 3 (rwrd.io/iuf9jqd?c )
* RAD Power battery ( radpowerbikes.com/collections/replacement-parts/products/rad-battery-pack-2021 )
* PETG filament ( amzn.to/3gV5fj6 )
Accessories on our bike:
* Bushwhacker Omaha - Bicycle Grocery Pannier (amzn.to/3x3ufud )
* Bike Mirror ( amzn.to/3A6sQFl )
* Bike Bottle Holder ( amzn.to/3dmprZ5 )
