Hi Dave,if you are interested i will buy your front motor with the controller.

Very interesting,how much cost?and what reduction they have?

Wow,if it works at 36v and its cheap,i buy one for sure.I think its a good idea to make a mid motor like this but with external controller at low price,its a really nice option to a expenseive bafang bbshd.

I buy it at eclipsebikes in england,really good price and he send me my unit reprogramed at 18A.really happy with this shop.Im thinking about buy a gsm mid drive with external controller to put in other bike,but i dont know how it works compared with the bafang 36v 500w reprogramed to 18A.I...

Thanks.anotherkiwi.In euskadi the weather its different that in barcelona,not super hot,but super rainy,hehe.

Thanks,guys.Im not sure about the motor size.By the way,anyone know the weight of the motor only?without crank arms or pedals,bare motor only.

Whell,if someone post some fotos of a gsm dissasembled,im really happy,thanks.And sorry for my english.

Look at the fotos of bbs01 and bbs02,you can see the smaller motor case(just in the motor side,not at controller and motor pack).

I ask this because i supose than the small bbs01 motor gets hot if i use it in high weather,like 32 or 34 c degrees.I like the external controller option,but if the gsm motor is small like the bbs01,probably its not good for use in summer in barcelona.

Not really,bbs01 have a smaller motor.

Same size of bbs01 or bbs02?

I like to know the size of just the motor.Its more like the bbs0 or the bbs02?Looks bigger than the bbs01.

Im very curious about this motor,for the price and weight looks a really good option.you use it with 36v 22amp controller?

So,in comparation with a bpm 500w,its the same torque without heat issues?sounds really good.

Really nice bike,man.

Whell,after reading some reports about the gsm kit,im thinking to buy the xiongda,just wait for more opinions.

At this moment im doubting about to buy a gsm or a bbs.

The first thing i do when my motor arrives is look for a chainring adapter.46 its really big.

Can smebody put a foto of the chainline and the chainwheel?For me its a really important thing about this kit.For me the 46 chainwheel its really to big,and i want to know if whe can put a bbs0x chainwheel adapter.Thanks!

As i see,the problems with this kit is electronics.I hope the version without controller works fine from the first day.
