Alternative brakes?

[andreashb]

Hi, I have recently installed a 3000w kit (mxus) on my bicycle. (btw it is crazy fast!!). But I cant seem to fit my rear brake calipers. I wont even fit the disk because it is so small space. I have tried to bend the frame, but I will not bend anymore incase it breaks. I wondered if it was possible to install v-brakes? Or do you have to have special rims to fit v-brakes? Is there any other brakes that could be used? Thank you in advance.

Regen rear brake might be your best option, after the better one of get a frame you can adapt better.

Your rim is compatible with a rim brake. You can mount a v-brake with an adapter plate,

or you can get a caliper brake of sufficient reach, probably 79-99mm.

Which of these options is easier depends largely on what kind of brake lever you are using. If it's long pull, get a v-brake plate. If it's short pull, use a caliper.

And keep in mind that most of your braking power comes from the front brake. The faster you go, the more you should rely on the front brake.

The drop outs are not parallel with your motor, and the articulated torque arm is weak. I wonder why the fit is so much wider than your dropout width. Either your frame is narrower than the usual 135 mm, or you did something wrong on the other side. With a single freewheel, the motor should fit 135 mm and let you use a disc brake.
