Works Well
Does the job without any issues. Good price. Don’t forget you will need a 32mm socket.

Perfect for Bosch Gen4
Excellent quality at a fraction of the price of a named brand tool. Fits and works well when replacing the chain wheel on a Bosch gen 4 motor e-bike. Don't forget it's a left hand thread!

Ok for the price
The tool works, and the price is good. But the tolerance is too slack, and it doesn't stay in the socket securely. A wrap of tape seems to do the job.

Fits Bosch Gen 4 CX performance perfect
Bought this after seeing a youtube video saying it will work with Bosch gen 4 and it's much better value and actually fits unlike some you can buy!

Right tool for the job
If you have the Bosch motor in your e-bike this is the tool for doing the crank up 30 nm

Fits Bosch Gen 4 motor chainring lockring
Bought to remove the lockring securing the chainring on my Bosch G4 motor and it fits a treat. Feel free to buy the one from ebikeshop.co.uk for £40 but this was next day delivery for £13.98 and does the job 👌👍
