    No pedal assist - what to check first?

    Torque sensor issues hmmm, not something I can help with. One could try a raleigh dealer for help. TS on hub bikes is a complication not needed. The fault could be the sensor or it could be the controller box.

    electric moped fault

    You need to think of the battery in the same way you think about pc's then. If you want a better battery well best to spend a bit.

    electric moped fault

    I find it is best when in a better frame of mind to get ones head around it if one can't take it in or understand, this is what I did when Guerney was helping me with the setting up of the JAVA download programme for this retched pc/laptop. Batteries and buidling etc,etc I find easy but...

    Easiest way to increase top speed from 25kph to 35kph on 250w fatbike

    The motor rpm is chosen for not only UK speed limit but also the EU and likely most other countries where the 25km/h rule is legal.

    Best kit for mostly off road commute

    If you go over 250w it's not just the short bit of road on the route, likely all the rest of the route is public access space. It's not just road legality if that concerns you legality means any bit of land that public have legal access to.

    250W 36V basic speed numbers

    The cheap kits like voilamart use speed control so PAS is all or nothing as max current is walloped in the motor in all PAS levels. e-scooter using throttle only will have different programming for a graduated controlled throttle to be used to deliver power, the same programming doesn't appear...

    Is there a gearing comparison table for hub Vs mid-drive?

    The dual drive was far form maintenance free and at times rather troublesome it also was the achilles heel for the Swizzbee that also used the dual drive.

    Easiest way to increase top speed from 25kph to 35kph on 250w fatbike

    As battery voltage decreases so will motor rpm slightly The hub will have max rpm for the voltage but once the voltage decreases so will the rpm to a degree hence the terminal speed reading drops.

    Solar trailer rides again!

    One question Matt are you using one or two batteries ? I enjoy reading these posts as I did when EPJ posted, like wise georgehenry.

    electric moped fault

    Ok start again, in all there are 14 pins call Black wire no 1 pin which initially is B0 or 0v (it carries no voltage) , the next Yellow no 2 pin is cell group #1 and the next Red no 3 pin is cell group # 2 and so on until you get to the 14th pin which is cell group #13. The 13 Yellow/Red wires...

    21700 cells,

    A genuine A1 Sam 50e is a min £4.25 cell, they could possibly be re wraps if they buy them cheap enough from factories as non top grade cell so spec B - E cells at a lower price point, these cells won't meet the Sam QC procedure so I expect they could possibly be sold off to third parties and re...

    electric moped fault

    For individual cell reading only move the first pin to the next unoccupied pin hole. So once you have reading for cell #1 Black pin and first Yellow, move the needle from Black pin to next pin (Red) the other side of Yellow, this is reading #2. Yellow then becomes the Gnd for for the Black probe...

    Is there a gearing comparison table for hub Vs mid-drive?

    A BBS01 250w is comparable to most good hubs in torque and amps so the best match for testing, one will find little difference between the two. One has to test like for like and not pick a superior wattage or current rated motor. A lot of the branded mid drives and kits will out perform hubs...

    Is there a gearing comparison table for hub Vs mid-drive?

    One can't compare a hub offering 450/500w up against a midrive putting out 800/850w of power. It needs to be like for like. In the early days of mid drive when they were equal nm to hubs, the hubs used to trounce the mid drive on hill climbs at the Bristol hill climb races.

    electric moped fault

    Read the first lines of #184 you won't get any readings from the bms side, pull out the wired connector fully and insert the needles in the female pins outs.

    electric moped fault

    You are counting the pins on the bms side , these aren't used for measuring. You place the needles in the pin out holes on the plug end which is wired, it is these wires that are soldered to the cells. There are 13 coloured wires and 1 Black, the battery is 13s so there has to be 13 readings...

    electric moped fault

    Sewing needles or dressmakers pins are fine, the pinstrip is a PCB strip or arduino strip. The pins are seprated by the plastic strip they are in, the former are likely easier to have at hand. If concerned about probes accidently toucing then in between the needles slip a thin piece of pastic...

    Battery charging - cost of

    Over all battery charging has likely gone up 3 or 4 fold as the cost was only 5p or so.

    250W 36V basic speed numbers

    Your average throttle from my experince isn't linear or gradual in use, they are either all or nothing and little affect trying to feather them. I no longer fit them to my bikes as find they are just more clutt ron the bars then being really useful, a good able rider shouldn't need one.
