    em3ev - controller needs to be changed or re-programmed?

    Hi bono, Mine probably did about 150 km. A few weeks, four charges, was very happy with it. I made the mistake of letting a friend take it for a ride, he couldn't figure out that the Nuvinci hub didn't like to shift under load, so rode up a steep hill in top gear by using full throttle :shock...

    em3ev - controller needs to be changed or re-programmed?

    Looks like mine has just blown, weird noise then the 'dreaded click', Paul was right on it, controller blown likely due to programming. I'm impressed by the EM3EV customer service and international respect of 'warranty'. Accept the replacement controller, he can send you images showing how to...

    E-bike noob after cargo bike advice

    Just a bit of a progress report incase it is any help to somebody- The Yuba Mundo V2 has a steel bottom bracket shell with unmachined steel in the centre, the diameter too small to fit the Bafang BBS02 through. I bought a 33mm hole saw, which fairly quickly cut away the excess steel without...

    Yuba Mundo FAT with BBS02 mid-drive

    You've seen this yeah? http://www.ichibike.com/blog/2014/6/8/Ichi_Blog/Fat_Electric_Cargo_Experiment_Pays_Off/ar/40/ I'm in the process of a similar build, with a V2 Mundo and less fatness. Waiting on the 750W BBS02, found a 26" wheel built up with the original Nuvinci hub for the right...

    E-bike noob after cargo bike advice

    Thanks for the help folks! I've been in touch with cell-man and have just ordered the BBS02 with the 50V 12.3 AH triangle battery. I've also seen a few builders replacing the spider on the Bafang to take standard 104 BCD chainrings, I think I'll look into this, the mundo has I think a 38t ring...

    E-bike noob after cargo bike advice

    Wow! You guys rock. I am amazed at the thought and time that you have put into replies. A few excellent points made- Front hub motor simpler to install than rear hub motor with the Mundo's 14mm axle. I had assumed that a stock torque arm would do the job but can see how a solution like the...

    E-bike noob after cargo bike advice

    Thanks folks! I don't think I'm quite up to 2WD yet :wink: trying to keep things simple. The Bafang BBS02 750W Mid drive is a very interesting alternative suggestion. It uses a bigger chainring, so I'd have to either push harder or fit bigger rings/IGH to the rear of the Mundo if riding...

    E-bike noob after cargo bike advice

    Hello collected wisdom of Endless Sphere! I am after advice before purchasing my first e-bike kit. I have just bought an early model Yuba Mundo (V2) Cargo bike with the intention of electrifying it to make a cargo and child carrying electric vehicle. My research so far has me leaning towards...
