    E-bike Catches Fire

    It looks like the battery was in a pannier. I've warned about that before.

    Newbie with battery questions

    That range isn't so bad then if it's only 10Ah and you used full power all the time.

    Half throttle 4 wire

    You have a speed control PAS, so you always get full power. You should see a different speed limit on each level.

    Half throttle 4 wire

    There are only two possibilities: green or yellow. If one doesn't work, try the other. If you want to test that the rest of the bike is working, lift the motor wheel off the ground, switch on, then short the red wire to the green one on the controller. That should make the motor kick up to...

    Newbie with battery questions

    If you read that, somebody doesn't know what they were talking about. The other thing is you get less power with smaller batteries because your average voltage is generally lower. Your range sounds a little on the low side, though it's difficult to say without knowing the exact conditions and...

    WANTED: E-bike insights to help student research project

    the Bosch model is fine and some of our continental cousins in Germany, Belgium etc. Agree with me. Some don't. the German forum is full of Bosch problems, like this one: https://www.pedelecforum.de/forum/index.php?threads/defekte-bosch-gen4.74310/ and this...

    Ncm Prague help

    I'm not sure what you mean, but releasing the speed restriction won't make it any faster up a hill, unless the hill is not very steep. There's no change to the motor's torque. If you need more torque, there are other ways to achieve that.

    Conversion kit.

    There are basically two types of rear hub-motors cassette or CST motors have the spline for the cassette. freewheel motors have the threaded boss for the screw-on freewheel. Although freewheels are available with 8,9 and 10 speeds, the practical limitation on most bikes is 7 speeds because of...

    Sanity check my thinking, paralysed by choice, please help!

    The number of ebikes you need is n+1, where n is the number you already have.

    Optimum wheel diameter for e-bikes

    The same motor will make more torque and less speed in a small wheel than a big one. It's the same as changing down a gear in a car. The manufacturers normally use motors with internal differences depending on what size wheel it goes in. So that they don't lose too much speed in a small wheel...

    Brexit, for once some facts.

    Twitter share price dropped 7% yesterday. Kicking out people they don't like is turning out to be expensive. It's now 15% down since they kicked out Katie Hopkins and started a mass exodus. #Twexit is still trending. Talking of social media, is anybody following Project Veritas? They've done...

    Wheels, Lights, helmets Upgrade Recommendations

    It's not really possible to upgrade to disc brakes, which would be much needed. You have no mount at the rear, nor on your forks. Adaptors don't work very well. You could exchange your forks for disc ones and have just a front disc, which night be enough, but by the time you've bought them, new...

    Hub motor swap from Bafang to MXUS

    Sorry, I was thinking of another thread. Reasons for losing sync: 1. Wrong setting in the LCD (only affects some controllers that have settings for phase angle and timing). If you didn't change anything, that's not likely. 2. Bad phase wire connection. 3. Faulty mosfet in the controller. 4...

    Tandem Conversion Kit

    A tandem with disc brakes should be the easiest to convert because you have so much room for everything. You might have to look at extending some of the cables, but it depends on your layout. It's tandems with eccentric bottom brackets and drum brakes that cause all the problems. For...

    WANTED: E-bike insights to help student research project

    We get asked to do these surveys about twice a year. They're all very similar, with too many loaded questions instead of open ones; however, I did think that this was one of the better ones. That's only comparing with the others. I didn't have much trouble completing it. I was a schoolteacher...

    Carrera Vengeance Display

    There are more than one version. is this it? https://www.ebay.co.uk/itm/SR-Suntour-HESC-Electric-Bike-ATS-Replacement-LCD-Display-/202997760467 There's a Dutch shop that I think sells them a bit cheaper, but I don't have the link. Anybody?

    Why so few hub geared bikes with belts ? Looking at Kalkhoff

    There are two sources of power, which are your pedalling and the motor assistance that combine together. That power can be shared between propelling you forward and turning the dynamo to work the lights. The idea of an electric bike is to get easier pedalling by adding power from a motor to...
