WInd power for when battery on the conversion runs out :eek:.

brake lever (sensors integral) for cable brakes , brake sensors for Hydraulic.

Wow, that looks like a proper barn find. An early TR-1 design. Does it have rear brakes ? Back pedal braking ? If so a rear motor will be out.

One sometimes has to make sacrifices with bikes and style.

Thanks egroover, yes I did see the enerprof ones and also a china uk warehouse seller, but none at silly low prices like the BBS. Until you posted that one I wasn't aware of the 48v 250w BBS01.

Egroover can you work your magic and find a 48v 250w Tongsheng at those prices ? The best I have found is one for £319.

Well done for finding the issue, just goes to show the dealers have no idea about the product they sell and are just box sellers.

Interestingly the 48v one is also listed as 250w and appears to be 15a as well.

This danish site give's lot of info on batteries tested independently Battery test-review 18650 comparator (lygte-info.dk)

5P means five cells are in each parallel string/group, so even with a reduced max 7a per cell the battery can give a peak 35a. This graph is for MH1 (single cell) if you intersect 3.3v about the min to go with the 7a discharge line one will see that the cell only can deliver approx. 1400mah out...

Which hub motor is that you are using ? The engineering is and looks very professional for a very nice installation did you machine the housing or was it done for you ?

Cells used are the 10a MH1 18650. LG MH1 10A 3200mAh 18650 Bench Test Results...safe at 10A but suffers damage | E-Cigarette Forum (e-cigarette-forum.com) Without knowing the BMS specs one can only speculate that the continuous rating will be 20a with a slightly peak current of 30a. As per...

It depends on the BMS rating and the specific cell specs used as each brand has varying cells of mah and current rating. Can you provide a battery link ?

34v for 13s is wishful thinking even manufacturers don't usually give figures below 2.8v per cell for min capacity values.

Being plastic it has probably set in a new position in the box, esp if something was pressing on it. If it looks a bit lop sided then find something to press on it/re- align it by leaving it so over night, the small hole might be ideal for a bit of string tie thru it and then the other end to...

I don't use nipple washers, if one uses rims made of cheese they might be useful. If a nipple pulls through then either tension or spoke length is wrong or a better rim is needed.

Although no damage will occur ( to the controller not so the battery if it occurred) it is best to use a proprietary connector like a deans or xt type so that wire tails can't touch, if the controller has bullets by the sounds of it the battery must have as well though likely females. One should...

Two locks are better then one, secure each wheel.

Use ryan's spokes (sapim strongs 14g) he is also ryan builds wheels, for rims I use bankrupt bike parts on ebay and use the holland made ryde z2000 in nice pale blue.
