Hub Drive Restrictor

[HobieOne]

Hi, I ride a Focus Whistler2 6.9 EQP with a Bafang Groove Next 250w rear hub motor. Speed is restricted to 25kmp and while this suits me most of the time there are occasions when this restriction is a real nuisance.
Can anyone tell me if it is possible to de-restrict a hub drive motor and if so, is it something that requires expert (bike shop) knowledge?
Looking forward to any comments.
Cheers
Bob

You would have to put in a new controller and a new display, one that can be programmed. You have a small motor and a small battery and not a lot of nm of torque. The lack of neuton meters means it is only equipped for low amperage, so the bike wouldn't really do well being derestricted. For your next bike, if you look at models sold in other countries, so the motor is dumbed down for your area but has the components for more speed or for off road use, then you would be better able to derestrict it. A lot of people in England buy Engwes because of this. Watching some of the YouTube videos on British ebikes might give you a feel for what's available. On the plus side, I checked where you are, to understand the restrictions, and you live in a gorgeous part of the world.

Yeah I agree. A Groove Next is a 30 Nm motor with a 36v battery. So even if you could dig into it, there's not much you can do with that little motor and low power battery.

This is all part of a proprietary Bafang ecosystem, so you can't likely swap in a different controller and display like you would normally. Especially on the Focus Whistler, which is a completely integrated, manufactured ebike. You aren't the first person who has come here and hit this brick wall.

Unfortunately, this sort of thing is the reason why people do DIY conversions... they stay in control of the thing they bought versus being shut down when they want a change.

Thank you for your reply Annieolnie, much appreciated. Now understanding the situation I will tolerate my bike's limitations, until I buy a new one and will then know what to look for. And thanks for your comment about Noosa Heads, it is truly a wonderful place to live. Cheers.

Thank you very much for your explanation. This was my first delve into e-bikes so didn't really appreciate its limitations. My next buy will now be a much more educated one. Thanks again. Cheers.
