    Third Tongsheng TSDZ2 installation. Too much assist for too much of the time!?

    That setting makes no difference in my case. It has been reported that on older units it worked but was deliberately locked in the more recent controller (but not in the vlcd5) to prevent users from turning up the power excessively as this resulted in warranty claims.

    Third Tongsheng TSDZ2 installation. Too much assist for too much of the time!?

    Two things I would suspect. 1. Recheck the 8 pin connector as there may be problems on tx or rx wires. Make sure no bent pins and connector is fully in. Also make sure there is no shorts /contacts at the damaged speed sensor connector. 2. It is possible to damage the calibration of the torque...

    Spokes

    If the rim does not have eyelets, you can drill (5mm) or file the hole a little bigger. It would of been great if you had the exact replacement, as you can often replace the spoke without even deflating or removing the tyre (or the wheel with v brakes) by reusing the old nipple.

    Chain jumping on smallest cog

    Many freewheels have lockrings and most can be dismantled to get at the smaller gears. I have often used a chainsaw round file to dress the offending cogs after fitting a new chain and works ok. The shimano ones are difficult to open as the 14T acts as a lockring but there is a way to loosen the...

    Bosch takes the L on right to repair for ebikes

    Your reply reminds me of a philosophical discussion in 'Zen and the Art of Motorcycle Maintenance'. The Author (Pirsig) repairs his own Harley whereas his friend John has no interest in the workings of his BMW R60. (Different personality types?)...

    Hub Motor and Wheel Size/Diameter

    Hi Andy. The problem with most ebike motors is that they use permanent magnets to create the magnetic field, so very little can be done to control the field strength as used with Ward Leonard above. There is a timing method (field weakening) that can be used but its not very efficient. Its...

    Help identify hub motor

    I suspect the '1801' element refers to manufacture date Jan 2018 as my daughters similar looking Bafang motor(On a Pendleton Somerby) was purchased in Nov 2017 and has BFY1708 H188 engraved on it.

    No connector between wheel motor and controller

    Hi. There is perhaps a second reason for fitting the motors the right way around. On many motors, the hall sensors pcb is designed to be at the cooler bottom of the motor. When motor is reversed, the hall sensors end up on top which is hotter. Anyhow, I often have changed tyres and regular tubes...

    Wierd Pedal Assist Problem

    I had a similar type (kingmeter) sensor with red led that started to behave erratically and finally totally failed. I did not know initially what was wrong but the bike worked on walk assist worked ok so I suspected the pedal sensor. Anyhow, I removed the sensor (by unscrewing the small screw)...

    Yose Power Hub- need a new rim!

    Yes, that rim looks good. It has no eyelets, so this means that the spoke holes can be enlarged a little if necessary if using original ebike heavier spokes & nipples. You cant change the spoke cross pattern if using the original spokes. Unfortunately, Brexit has added difficulties, so you need...

    Yose Power Hub- need a new rim!

    Hi. Using the old spokes has worked out ok for me on front wheels or where the rider in light. Rear spoke breakage can be a problem with heavy riders. Choices in rims can be limited. You left out two important bits of information that helps to select a rim. The first is do you use a disk brake...

    Battery capacity and longevity

    I think we can reasonably estimate the expected battery life. Your battery is 48v X 13ah = approx 620watt hours and depending on your weight and fitness and use would give approx a range of 50 to 80 km (or more for some). I would get about 60 km per charge on that battery. Many batteries are...

    Electric bike Cost

    I share my car at the moment with my son that needs it for his work so I have no car during the week. Hence I do a lot of riding, clocking up over 10,000 mile last year. I generally do almost all my riding with hub motors (which seem to last forever)and run my batteries at 41 volts most of the...

    Bike cutting out when battery on 3 bars

    Hi. Just looking at the battery photos. I'm not sure how mechanically well put together that pack is. Anyhow, I would very carefully both visually and perhaps with insulated probe check all the welds of the cells in the 11 group. You could also try measuring the individual cell voltages in this...

    Electric Pendleton Somerby problem

    From your description, it seems a motor hall fault but recheck the light combination. Make sure the motor cables is fully pluged in at the chainstay and at the rear rack beside the controller case at end of battery. Any damage to cable where it enters the axle? On my daughters pendleton with...

    Battery health

    I have a phylion battery (supplied with Halfords bike) with a 'smart BMS' with an instruction to give a full charge/discharge cycle fully when new so the 'coulomb counter' in the BMS can calibrate and presumably give a more accurate reading on its state of charge/health/usage etc. The BMS has...

    Bike cutting out when battery on 3 bars

    Hi. Some points that might help. That's a big battery (20ah) so it could take more than 'a few hours' and up to 10 hours to fully charge if you have a 2 amp charger.(for example) If your battery is worn, there is a few settings that may help for the time being. The first thing I note is that...

    Ebike <2500 EUR for commuting + weekend fun in a hilly area (Dublin)

    Hi. Since Brexit, unfortunately, Irish people buying from the UK has extra taxes and complications. Anyhow, one possible recommendation from Halfords 'Black Friday' sale (Liffey Valley or elsewhere) is below...
