How quickly the pedakl assist kicks in is down to the programming logarithms, some controllers are better then others. One can carry out some basic checks to see that the PAS is working correctly. 1. Ensure any disc is firmly fixed and not loose or can't rotate freely on the BB axle. 2...

That's a re-cell job. Tbh you may need better cells then Sam 35e for 10sp2p, it really depends on the max current one draws. When deciding on a cell one has to consider the current draw one uses the most and then min cell discharge. As an example if one was maxing a 10s2p battery out at say...

It doesn't matter if a 250w hub looks the same as a 500 , it is what it is marked as. There is nothing debatable about power 250w means 250w rated, we know motors will take more power that is why some hubs are marked 350 or 500w for other markets.

There's no 'not strictly legal' about it at all, 500w motor and throtlle both illegal end of as a pedelec.

Tbh I don't see a need for a throttle with a 22a controller or that case any controller, what ever the reason just omit it and reset the C5 to max. 06 is a phase error code ,so connectors or even a bottle neck for the current to flow. Are the controller wire gauge thinner then the motor phase...

If having issues speak to Wisper about it, one will find them quite good at trying to help out.

How about adding a kit to a cargo bike, there's a nice yuba mundo kitted out for one kid on ebay at the mo, start bid is £400.

If the display is damaged wisper bikes will have replacements.

In eire or N.I a throttle is illegal so one coul dbe prosecuted for motoring offences. Electrically one needs a battery for testing functionality. The bike will work with any generic 36v two wire battery connection. Whether one will find an exact style battery to fit depends on the case type...

Be careful refitting the connector, both parts have an embossed arrow on them. Align the arrows opposite each other and firmly push them together with no twisting, the (male) motor side connector also has an embossed stop line so the this must be up against the female connector end.

Nice job though, a very skilled person indeed.

No that's not it, that is a just a wheel nut dust /moisture cover. Usaully one follow thta motor cable unitl it comes to the connector, it may be a case yours is at the controller box. Most hub motor bikes have the connector 6 - 8 inches along fromt he wheel then another longer cable that...

Regarding the bike speed, EN15194 allows for 15.5mph/ 25 kmh cut off assist speed +/- 10% so one can have a speed reading of 17.05 mph or 27.5 kmh. My 250w tsdz2 cuts off at 17mph so I wonder if Tongsheng have taken this in to account and programmed them as so in line with EN15194.

Be very careful with throttles and unrestricted bikes, it is likely we will see more prosecutions occurring regarding ebikes. One guy in Wales was fined a meagre £600 and had 6 points added to his licence recently and another in London is pending.

There should be a connector within 6 - 8 inches of the hub motor axle often cable tied to the front RH fork, it might be tight but will pull a part.

An ebiker has been reported for motoring offences, the suspected (seized) ebike was illegally tampered to assist over the 15.5mph cut off. This has come about following the ebike rider colliding with a pedestrian on Park Lane and the Met have reported them for no licence or insurance. The...

The pic doesn't help much, how many magnets on the disc ? I can only guess but as it appears to mounted behind the chain wheel, try C1 setting on 0 , 1 or 2 if it has less then 12 poles. If it has 12 poles then try C1/3.

If you don't know take some good clear pics of the PAS installation so we can see what is fitted.

Tell us which PAS model you are using so the correct parameter can be set.
