My bike won't go faster than 50 kmh. How can I change the speed limit? Anybody knows?

Thx, found the wire and cut it. It's fast and amazing now.

Should the front and rear light be on the whole time, day and night?
I can't see any control switch for the lights.

Yes, it's a little wired.
I will be happy to see your solution
Thanks

In some markets, having the lights wired on was/is a legal requirement.

My country had the rule for safety reasons, in recent years they dropped it but many manufacturers still seem to sell the hard wired headlights.
I guess if it's just easier to build them the same for every market, cheaper probably too.

Some of our imported bikes just had the light switch still on the handlebars but the actual button was cut off!
Looked dodgy but it was the laziest/cheapest way to make sure they were road legal here for importers.

Thx for the explanation.

Another question: is the chain noise that comes from the chain is not consistent, goes in waves, up and down, specially when the throttle is off.
Anybody paid attention?

My opinion here but the O-ring chain is way overkill for this bike and robs you of watts. I swapped out for a no O-ring and it's quieter and faster. but you have to keep it clean.
