Some controller can be dual mode , all the ones I have bought are one or the other.

It's not clear but looks like rear disc brake is out as no braised on fitting for a calliper, though rear HDB isn't to important as most braking force is at the front end of the bike. Front disc brake would need new forks with calliper fitment and a new disc hub built in to a rim and a front...

Much the same as the other joker in the other thread who is now calling me by rude names because I also called him lazy. Ignoring requests I think you are right, not worth wasting our time to do their research.

I suspect he has the top one, form his childish replies.

Any one who comes on here asking for help and then can't be bothered to upload a pic of a specific bike they have is as I said just being lazy and doesn't deserve further help, esp if going to insult or abuse forum users willing to offer up free and helpful advice. If you are upset by being...

Sounds like a company selling stuff they know little about or understand.

Square wave controller cannot make use of sensors, there is no software/components in /on the pcb to allow this. Bafang hubs like KT controllers are either 3 or 9 pin, please listen. The controller is square wave, the motor connector is 3 pin so hub is unsensored. Nothing wrong with it just...

Well over 2k for a funky looking bike using generic electronics. Might be fun in the snow and mud but it isn't a 2.2k ebike !!! A Bafang hub & controller with C961 is bog std Bafang stuff.

Have it your way then, I will simply treat you with the contempt you deserve.

A lot of posters expect us to do the homework for them, lazy posting with no pics of the bike. Why should we waste time looking for a bike that might be or not be the same.

If the controller is square wave so the hub be unsensored (3 pin) , like wise if the hub was sensored (9 pin) the controller would be sine wave. Providing a kit with sensored hub and sq wave controller makes no sense.

As vfr has said the Yamaha uses CANbus/handshaking between display, battery, controller & motor, like Brose, Bosch, Shimano and others you are tied to expensive in house spares. Non of these can use off the shelf generic components unless one is an electronics wizard/programmer who can back...

Although tight can the wiring not wedge in the wedge shape above the controller ? Even with an under seat bag I still have to wedge it in above the controller.

How about showing the forum pics of what you have, otherwise we will not waste time looking up something you are too lazy to post.

All a throttle does is draw max current from the controller, it will certainty drain the battery quicker but no more then riding in max assist with current control or any speed control controllers. Generic controllers barring the BBS ones aren't usually re programmable without software.

If it is a silverfish battery a mounting kit can be bought separately. other wise use a velcro strap to keep it form moving about.

Best advice is don't do it with a crappy ali bike frame.

9 fet KT's are available in both flavours, I have a 22a & 25a 9 fet in sinewave. One has to know what to look for before committing to buying. The chance of a kit being supplied with a 9 fet Sq wave/unsensored is more likely though as they may be a bit cheaper.

How about the hill climbing challenge that used to take place in Brizzol, a hub bike beat a Bosch drive to the line.

Still not safe without Torque arms fitted, one each side. The tabbed washers are just for hub location/orientation, similar to those that are fitted to hub gears like alfine.
