my light weight racing-bike Total weight is only 12,7kg "ready to race" Motor comes from "Shengyi" with 350rpm and only 2,2kg . The Motor I have ordered at my friend in China (www.woaczh.com) basic bike is a Radon "Spire" which has only 7,5Kg and is outfitted with complete Shimano...

I agree with @flecc that the only solution seems to be a rear-hub. On a cargo-bike like that I would suggest a powerful motor like Heinzmann or BPM-CST or Bionx-D Frank

Hello Gurnard, I agree with you that the failure is made in the first place at BMS with the stupid packing but the question is how to deal with it now because I don´t belief they will send you a new Motor. I just told you how I´ve dealt once with a similar problem. Even you complain about them...

Hello Gurnard, I guess that bend back is the only choise you have because I dont belief that BMS take the motor back and if they doe so it will take a long time and you must spend again money to send back the package (40-50GBP shipping-fee) and then waiting 4-5weeks waiting before it arrive in...

The Heinzmann motor is very powerfull and have not so much heat-problems as the bionx. I would prefer Heinzmann much more as bionx Quite, Powerfull, runs up to 38km/h with unlocked controller or up to 50km/h depending on the typ of motor in 28" wheel The spare-parts are "cheap", in compare to...

maybe you forgot how to do a little math? ;) it´s on a 20" Wheel approx. 32km/h depending on the tire-size regards frank

yeab this description is correct and for this I don´t like the motor. Sorry I couldn´t describe with my littel english;-( Of course it works for coaster-brake but it is just a cheap chinese solution for a coaster-brake bike but not a good one. Thats also the reason why I say you must setup 9...

I found it here in chinese taobao: http://world.taobao.com/item/520804566957.htm?spm=a312a.7700714.0.0.r1GNm2#detail but can´t say anything about quality but looking is good best wishes frank

I don´t think it is necessary but I would not go for magnets melted to the Brakelever and so on, I would use a ready set like this one for bbs Motors

Hello shemozzle, the Ring is just a pas magnetic fields inside like the pas at the normal BBS only that here is two rings for a maybe faster reaction or one ring is for the forward pedal and the other one for reward use the coaster-brake because the electronic need for this a signal If you...

I´ve no idea whether the Heinzmann direct-drive is popular in UK but maybe some people have interest in it. I´m a fan of Heinzmann DD-Motor because very powerfull and silent and have not so much heat-trouble as the bionx on step hills. I have a prerelease version of the new Heinzmann Software...

Hi shemozzle, bafang bbs hasn´t torque-sensor only max-drive is with torque-sensor Throttle connector depends on the controller, which version the retailer order at the factory, in germany usualy is no throttle connector because the user don´t like it but in Uk or US throttle is popular so I...

Hello I have a get a new toy I like to share, a bafang bbs coaster-brake motor I´m not a fan of coaster-brakes but apperently a lot of people waiting for a coaster-brake middrive conversion-kit as always on my website you can fínd more details for this motor, from outside it look like a...

as promised, so now I have the 190er Fatbike-hub motor of Bafang installed and tested. I have to say the motor is very good and has a high torque. This engine convinces me until now and without any ifs and buts. Frankly, I would always buy me compared to the mid-engine the hub motor, much...

Hi tezdread, on my Motorset you don´t need to make thread´s to the motor, I was considering this way how Doug made it but I come to the conclusion "to complicated". That´s the reason why I chose the way with welding, nobody need a expencive tool (thread-cutter) for only one time using. So I...

160front and 180rear? I assume that your measurement isn´t correct standard for fatbike is 150mm front and 190mm rear. Before the standard was 135mm front and 170mm rear. Bafang have two hub-motors for Fatbike one is for 170mm dropout and the other is for 190mm dropout´s 250watt -->500Watt you...

there are several different motor´s for fatbike´s For my self I´m hoping to receive my 190mm Fatbike-hub from Bafang within the next days and then I´ll post as always what I think about. Also wíll say some words about the hub-motor in compare with the bafang-bbs for fatbike

hi folks, some people in germany asked me whether it is possible to run a bionx-SL with a replacement controller like a cheap sensorless controller or even a sine-wave controller from china. Reason is the Bionx-SL is now mostly out of warranty and often brocken, specialy at the torque-sensor...

Hi Eddie, I guess we have that in common but I sell the bafang bbs 100mm bottom-bracket conversion kit and I thought it would be a good idea to know more about fatbike and not just sell the kit without knowing about ;) But I must admit that I had a lot of fun on riding across the forrest with...

you are right but I just want go on the road after install the motor and for my weigth of 130kg I thought put some psi extra to the tire but in between I let some pressure out of the tire because I took a ride in the forrest and my ass gave the signal of to high airpressure in the tire ;)
