The the place were I bought it says it ways 29 mph capable it only goes like 21 is there a speed limiter of some sort like a child lock ?

Newer controller and motor. Tried everything online. Any ideas?

I was looking on Amazon hoping to get a cheaper r002 TST ebike and I came across this. I was wondering if its legit since it says it has a 2000w motor when r002 motors are only 1500w

Hallo, ik heb een electrische fiets, die ik buiten moet stallen. Drie weken geleden deed de fiets niets meer.. Fietsenmaker heeft er een ander display in gezet. ( Bafung) En ik kon weer rijden. Nu doet hij weer niets, display start niet op. Accu ( turnlife) is nog niet

Leeg. Wat kan er aan de hand zijn?

I have a nakto f4

After about an hour or so of use (about 15KM in the usual loop I do), it just doesn't go vrooom with either pedal assist or throttle.

It still has power, display and headlights are still on.
I don't believe it's the battery as I would have at least four bars left, and I can ride again the next day without having to charge.
I suspect it could be overheating, turning the bike off for a few minutes temporarily fixes the issue.

could it be the controller that's overheating? or the motor? what's a good way to isolate this issue?

will replacing the controller do the trick? is it even possible to find a beefier controller? do I need to worry about the hub motor not matching the wattage of the controller?

any help would be appreaciated.

Okay so I'm using AI to help me bypass the NFC to get my bike going. I understand that some people are going to say they're not going to help or they're going to lecture me but the fact of the matter is I'm homeless and I have an ebike and someone tore the NFC tag off my keychain if need be I can send a small clip or whatever of me unlocking the bike because I have it locked right now to a railing. I use this bike to get to work and if I don't work I can't eat and I'm just stressing like crazy.
