Has anyone on here fitted a BBS02 or TSDZ2 motor into a Specialized Fsr frame. The frame dates from about 2007 & has the straight downtube & standard BB. It measures about 18 inches to top of seat tube. The frame triangle is a bit tight but may just take an HL1 battery. I will have to try one...

Hi. What do I need to upgrade BBS02 36v 500w with C961 display to 48volt or would it be worth replacing rather tired Samsung 29e cell 14.5 Ah battery with a 17.4 Ah one with 29e cells. I know that 29e cells are pretty low discharge but would the 10s6p supply more power than the 10s 5p I am using...

I am looking for a good quality HL 1 36 volt battery, I was going to order one from Eclipse with 30q cells but they are out of stock. I wanted the HL1 because I have one on another bike so it would be handy to have two the same. Can you recommend a good UK or at least EU supplier. Has anyone...

I have a Tong Sheng 36 volt 500watt motor in a Giant Revolt gravel bike. The battery is a Woosh HL 15 amp hour, which is nearly four years old, it still holds a reasonable charge. The maximum charge seems to be 41.6 volts. Charging has become rather strange. I left it on charge after a 15 mile...

I have bought a pair of Steps crank arms, to replace the standard Tongsheng items which had a ridiculous Q factor of 212mm. they came with retaining bolts that tighten using a socket rather than an Allen key. Is there any reason why I can't use the original Allen bolts? I don't want to have to...

I have a Tongsheng motor powered by a Woosh 36v 15ah battery. When I turn on the display everything looks OK. I wait for the Spanner symbol to disappear the motor pulls away fine, but only for a short distance. Maybe 100 metres or so, the display goes blank & no power. I stop & turn back on &...

I have read that this works on some bikes but not others. Does anybody know if it would fool the speed cutout on a 2017 Haibike sduro hard 7 Yamaha motor? or a 2017 Giant Dirt e 2 with Giant / Yamaha motor? I was told by the local Giant dealer that the Giant version of the motor was not easy to...

I know that this unit had very mixed reviews when it first came out, but I would like to hear what owners feelings are now. Were all the early units 250w? Is the 350w model different? I seem to remember reading that the chain line is not good, but is it any worse than a BBS with standard...

I am looking for a rear hub motor in either a 27.5 or 700c wheel. The SWX02 sounds about right. I am surrounded by hills & I don't think the little 08 motor would be up to the task. Do you have any wheels in black? I also read that you have a Q128h kit in a test bike. Is that for sale? Finally...

The reason I ask is that I have seen a Bosch performance line bike 2016 model that looks interesting, but as it was built possibly 18 months to 2 years ago & has been in a box without ever been recharged, is the battery likely to have lost its ability to take or hold a charge? Steve.

How much difference is there in terms of performance between these two motors? I have seen a brand new AVE 2016 bike which is very well equipped for the price. I imagine it must be at least 18 months old. Will the battery have come to harm through lack of use? Steve

Any opinions on Panda 250w or 500w kits. What motors do they use etc.? Steve

Looking for a rear hub drive cst kit. The Woosh is attractive because I already have a bbs02 kit with HL battery so if I wanted to go for a longish ride I could take a spare battery to extend range. The kit is also £300 less than the Oxydrive. What are the differences between the two motors...

I have a Bafang bbs02 36v 500watt motor with c961 display. The manual states that it can show speed, average speed & max speed, but I can't find anything relating to how to do this. All it shows is current speed. Am I missing something or does this only apply to some models? Steve

I have an old ( circa 2005 ) long cage rear mech. The only markings I can see on it is "Integrated 8 SIS" I am running an 11-30 cassette, it is OK with this. Does anybody know if it would be OK with an 11-34 ? Steve.

A Haibike Sduro hard 7 has been advertised on Gumtree for a few days now. Hardly ridden, works perfect etc. £870.00 Ad shows a contact in Ingol near Preston. Sounded too good to be true, but it's only half an hour away so I sent an email, heard nothing, sent another email a couple of days...

I bought a Cat Eye Strada wired computer with cadence read out, to help me keep my BBS motor in the power band. When I ordered the Strada I didn't realise how small the screen is, the speed reading on the top line is just about OK for my eyesight, but the bottom line is small. I found myself...

Due to lack of space in the triangle of a Norco Charger frame, which is fitted with a BBS02, I have fitted my HL battery inside a pannier. Will it be OK to carry waterproofs etc. in the same pannier, or might the battery overheat ?. Steve

I need to extend my battery cable. 36v 15 ah battery. bbs 02 500 watt motor. The cable will be around 700mm long when extended. What diameter cable do I need?

I have quite cleverly generated a large spark, I have a 36v HL battery with push in connectors inside the metal casing at the end of the carrier. The carrier was not connected to anything. I slid the battery onto the carrier & hey presto a large flash on removing the battery & the cover on the...
