I replaced the freewheel on mine with a new one that was the same tooth count as the original. I really can't hear it much.

You really want the pedals to work if you want to avoid issues with stupid cops. Also handy when the electric drive fails. On mine, I can assist the motor up to about 20mph in top gear. Beyond that, I just ghost pedal to keep the cops happy.

I can tell from your Whr/mi that you were having fun. If you keep the speed down below 20mph, you should be getting closer to 20Whr/mi and you can ride till your butt hurts.

Cool, maybe a video on your next run? Some panniers over the batteries would look the business I reckon. I agree, pedals are a must or do you live in an area where it’s not a requirement? I know Ultra motor made an A2b excel with foot pegs if you can find one. The joys 20inch wheels, I fitted a 70T and that barely helped.

Would "stealth" the bike quite a bit.

Wow, I had no idea, but that's pretty wild.

It's like they attached EUC pedals to the frame. Hrm...

Even if I could find one, it looks like that's welded to the frame, so not something I could just swap out.

Cool, I've never seen one like that. Around here it would be legal on the street, but not on the trails. You'd be sort of screwed with that one if you hit any kind of hills like I deal with. Great for flat ground.

I believe I read it has a higher power out, not sure. You could maybe buy some unicycle pedals and attach them somehow. I saw a white one once for sale here in UK going really cheap, I guess no one wanted it because of these stupid laws. If I could go pedal less it would have to be the BREKR MODEL B. Dream bike, attaching pedal would be a nightmare I imagine.

Yes, the A2B Excel was labelled/sold as an 'Electric Scooter' and appears to have been fitted with an 800W version of the UltraMotor.
I guess the controller was in the frame:

It says main battery 48v, so that's how they got more power. I ran mine at 52v for a year before I did the external controller.

Ended up putting a chain back on, but I also picked up a shimano freewheel to replace the DNP hoping it would be quieter (reviews said it would be) and it definitely is.



And it's even better once mounted on the bike. I doubt it'll be audible at all once I'm moving along.
