Title: rarunner bike throttle cutting power
Post by: ozgurA on April 06, 2021, 09:48:30 AM
I just bought a new one and I think it supposed to move without pedaling on PAS0 mode?

no, pedal assist mode 0 is no motor assist - zero power assist even if you pedal.

On my Radrunner, PAS 0 let me pedal without engaging the motor. The throttle would give me motor power as needed. When I moved the seat aft, I found that I could pedal harder, and I enjoyed it. As much as possible, I pedaled with only the sound of the tires. On a street with motor traffic, I'd use throttle to get up to 20 mph faster. I'd use intermittent throttle on a grade where I couldn't maintain speed with the pedals, and it was available if I wanted to rest.

I switched to the more powerful controller through Bolton. I love the display but regret the fact that if I want a bit of throttle at PAS 0, first I have to switch to PAS 1. Then I go back to PAS 0 to pedal in silence.

Thanks for the answers. This is my first e-bike therefore I have lack of knowledge regarding general e-bike behavior. Let me ask this question first. Does the Radrunner allow riders to go without pedaling only twisting the throttle? If yes then I have a problem. Thanks

If you need to pedal for the motor to run, that's Class i. Adding a throttle makes it Class II.

I unplugged my throttle cable, about 6" from the throttle. The motor would not run unless I pedaled. I have an aftermarket controller. Somebody else would have to tell you if it would also work with the stock controller.

If you just bought it you should consider calling the support folks at Rad. They are awesome and will probably be able to help you more quickly than posting here!

Here is the answer from Radpowerbike EU, thanks.

"You have probably informed that Throttle can go full speed, and that is true but here in EU we call that Twist Power Assist.
Twist Power Assist on the European versions of the bikes is limited to 6 km/h. This means the Twist Power Assist on your bike will serve a walk assist function, or to give you a boost when you are starting off. This limitation is done so that the bike can be categorized as a standard e-bike throughout Europe, and does not require any registration or insurance."

I didn't know about Twist Power Assist, but I have noted that my aftermarket controller can be programmed to limit the throttle to 6 km/h. It makes sense. I like a bit of throttle to get started. I have a shortcut across a grassy drainage ditch. Twist Power Assist would help me walk the bike up the bank.

Yeah, that sounds correct for an EU version.
