merhaba 1500 watt motor aldım ve carraro bisiklet bağladım. İki hafta çalıştıktan sonra motora gaz verdiğimde tekerleği bisikletten ayırıyor. Bu konuda tecrübesi olan var mı?

"hello, I bought a 1500 watt motor and connected a carraro bike. After two weeks of running, when I accelerate the engine, it separates the wheel from the bike. Anyone have experience on this?"

Possible three issues here.
1.Drop outs are now snapped/broken.
2. No torque arms fitted, requires one on each side .
3. Drop outs also not filed deeper in the first place.

Drop outs need solution 2 & 3 as the minimum.

Do you mean the wire from the motor? If this is broken or damaged you will need a new motor and don't forget the torque arms and filing the dropouts.

I suspect the controller is also damaged, when the wheel span out it is likely the motor wires shorted when they broke.
It is possible to re wire with a new motor wire but one will have to open the hub and do a bit of work and soldering to repair.

The bike axles are for 9mm QR ones and the motor hub axle is 14mm deep, so it is 5mm over all deeper. The axle will need to sit deeper in the drop outs by at least 2.5 - 3mm or at least all of the flat side of the axle needs to be sat in the drop outs.

Tatmin edici açıklama için teşekkür ederiz. Bisiklet servisine gittim ve onlara dokunmadığımızı söylediler. Açıkçası bahsettiğiniz işlemi nerede yaptırabilirim bilmiyorum.

With ebike hub motors one has to learn to do his own repairs, in the UK if someone is stuck then Woosh bikes might offer a repair. Most bike shops haven't a clue how to repair an e bike and the ones who sell big brand names are worst of all as they don't know how fault find a problem, the machine has to do it for them.

1500 watts, good grief that's not an ebike it's an electric motorcycle

Not surprising it's pulled the wheel out of the drop outs as the motor is probably six times the designed power limit of the bike.
