Hi all?

I have a rad city 3 that I?m running with an aftermarket 52v battery and original RAD controller and display which I?ve read  should be ok.

The bike runs fine, but the display is set up for 48v battery, so it dies abruptly and completely at 2-3 bars, since the BMS is set up for 48V, which can drop significantly lower than 52v without damaging them.

Does anyone know what voltage  each battery bar represents, so I can better guess where my battery Level is at?

Thanks!!
Ben

Hey all!

Looking to pick up a basic factory headlight for my bike. If you've upgraded, and want to sell your old one, please message me!

I'm in the pnw and can pick one up at Rad in Seattle, but would love to buy used.

Thanks!

Hi all!
I have a 2019 radwagon that I bought second hand. It's been modded to the point where all that's original is the frame and the rear motor wheel, which isn't connected to power since it now has a Bafang midrive motor... so now I'm trying to figure out how to reuse the rear motor wheel to electrify another 26" mountain bike!

• I was going to to try and buy a used Rad display/controller, but the issue is that Rad says the 2019 wagon isn't compatible with other Rad models controllers or displays.


• How can this be? If the Bolton kit is plug and play across all models, how can the Rad controllers also not be interchangeable?


• (yes, I know I could just BUY the bolton kit, but this is a spare hobby bike for when friends visit and I don't want to invest $200+ in it)


• What throttles are compatible with the rad wiring harness? I bought a half twist for the Bafang motor that I really like, but have no idea how to check if it would work.. the connector looks very similar. Do you have any to recommend that you know work without any soldering and splicing?

Thanks for any input!

New to the forum, so please direct me if this belongs somewhere else!

I bought a heavily modded radwagon from a friend (bafang mid drive motor conversion) and it still has the original rear wheel with motor. I'm going to get a new rear wheel built to cut out the extra weight and magnet drag, but am wondering the following:

1) what would I need to build out a separate ebike using the radwagon wheel/motor? I know I need a controller, a screen, and a battery, but if I want to run it throttle only, do I need a pas sensor and wheel sensor fro speedometer? Any recommendations on a bike frame to build onto? Do Rad screens and motor controller show up second hand? What type of cabling do I need for thai build?

2) any recommendations for replacement 26" rear wheels for the radwagon? The original has 12gauge spokes. To have one built will be over $200, so if there's a good resource to buy a sturdy rear wheel for a cargo bike I'd appreciate your suggestions.

Thanks to all!
