My (now quite old) GSM mid drive (from woosh) needs a new chain ring. Does anyone know if the bbs01 chain ring would fit? The issue that has developed is the chain keeps jumping off. So I was going to replace the chain and ring ( and possibly the cassette).

I've bought a very cheap front hub motor (250w 36V). It takes about 4 revolutions of the pedals before the motor kicks in and it is intermitantly stopping. I have tried with and without the brake cut out (to rule this out). I've moved the PAS closer (it's currently 2-3mm from the ring. The ring...

I need to extend a power cable from the battery. Can anyone recommend what sort of cable I should get? It’s a 250w36V system. The controller is marked 17a. Thanks

I want a cheap conversion for the school run. 6 mile round trip. I was looking at ordering something like this https://www.ebay.co.uk/itm/254630141528?hash=item3b49239e58:g:o~YAAOSwdQdgXVOX Along with a low capacity battery...

Hi, Can anyone recommend a low weight, low resistance front hub kit? We have two bikes to convert, one with 26" wheel and one with 27.5" wheel. I've ordered a swytch kit but then I thought I might be able to achieve the same for less. I've found some fairly light batteries on ebay. These are low...

My bike has been stuck at my holiday home through lock down. I got it out at the weekend to find the pedals stuck. It’s a Marin Stinson with a GSM mid drive conversion. I’m going to try and remove everything today. Is there anything specific I should look for? The motor is fine and turns the...

I remember reading a little while ago about some really light weight Hub motors from China. I think they were around 1kg. I’m keen to try a really light weight conversion can anyone comment on the longevity of these motors, could they be paired with a Hoverboard battery (36V 4.4mAh), small...

i need to fit a battery to the rear rack. As you can see from the link the bike has very high bottle mounting points. https://www.marinbikes.com/gb/bike-archive/bikes/2017-stinson-step-thru Would it be crazy to try and mount a bottle battery to the rear rack? I would like the battery to be...

id really like to convert my second bike but be able to put it back easily. My original has a gsm mid drive which is fab (most of the time). If I went for a front hub motor could I swap the wheel for a non motorised one easily?

any suggestions? When I turn the cranks there is a noise like something is grating. There is also slight resistance. If I had to guess it would that something needs greasing. I don't feel amazingly confident opening it up?

im really happy with my GSM mid drive convertion. It's been a revelation and I love using my bike. The only downside is the weight. The bike and kit is really heavy. I want to convert a second bike, is there a lighter alternative?

Has anyone see or tried one of these? http://go-e.bike/en/shop/ It potentially looks great, but would really like to see how people find it in reality. The weight us very appealing, as that's the one downside of my current conversion. Also put off by 8-10 week delivery!

hi, The lock rings came loose today, I've tightened them, but noticed there's a slight clicking coming from the pedals. Any suggestions of what I should check? Otherwises it's running really well!

Hi, Someone posted in a thread a calculation to work out how much of the battery had been used. It had something to do with timing how long it took to recharge, but I can't find it. Can anyone help me? Thanks

im having real problems soldering the wires together. I have a 40w soldering iron that melts the solder. However when I try and heat the joint to draw in the solder and fix the joint it won't melt. The wires are getting shorter with each attempt. Can anyone suggest somewhere I could take it to...

Am I correct in thinking to make a conversion road legal it needs a 'plate' with certain details on it. As a self installer can I put a sticky label on it, if so which details does it need?

I want to get a set of tools just for bike maintanance (mainly so I can actually find them when I want them). To start with I intend to buy a set of hex wrenches (L shaped), crank puller, cable cutters, screwdrivers, then add to it as I need the tools for specific jobs. Is it worth buying park...

i've install the brake levers that came with my GSM, but don't really like the look of them. I've seen that bafang sell a sensor that can be retrofitted to existing levers. Would the plug that goes to the lcd be the same? The GSM one is red with two pins.

is there a way to reduce the vibration in the battery. It's a rack battery and rattles quite a bit over bumps. Can I pad it with anything?

My GSM kit is arriving tomorrow and I just want to make sure I have all the tools ready. I have a torque wrench for the m33 nut, can it be tightened with a normal socket set.
