    LG cells and appropriate C rating replacement

    I’m in the uk so wouldn’t use that shop but I’ve got a choice of a few good brands for between £2.50-£3.50 per cell so I guess something at or over 15A discharge should be as good as the original battery. If I went for something like the Samsung 30Q I’d be doubling the packs capacity in theory...

    LG cells and appropriate C rating replacement

    I’ve got a Black & Decker strimmer that uses LG LGDAHD11865 cells, the battery is a 36v 2ah pack so 10 cells but after a bit of searching it seems the cells are actually 1,300mAh but I can’t find the info on what the discharge rating is for these cells. I’ve had it for about 5 years so the...

    Single shaft spoked hub motor for fatbike/trike wheel - Does it exist?

    Yes that is what I meant by fat, I think they look cool and should be great off road although if it narrows my motor choices down too much I might have to forget about the fat tyres. I wasn't sure what wheels sizes they come in but I think the recumbent trikes seems to use either 26" or 20" as...

    Single shaft spoked hub motor for fatbike/trike wheel - Does it exist?

    Thanks that's exactly the info I needed! The first link to the tadpole build is what I was thinking of for the front wheels so once I'm ready I'd contact grin tech about those all axle hub motors as they seem able to machine up the torque arm fittings and whether that motor could be fitted to...

    Single shaft spoked hub motor for fatbike/trike wheel - Does it exist?

    I'm trying to come up with a design for a very capable all wheel drive off road vehicle, from my experience anything which is only front or rear wheel drive fails in extreme wet, muddy or hilly terrain and looses traction. Due to a progressive illness I'm looking into options which will allow me...

    I'm trying to come up with a design for a very capable all wheel drive off road vehicle, from my experience anything which is only front or rear wheel drive fails in extreme wet, muddy or hilly terrain and looses traction. My idea is taking a tadpole style fat trike and turning it into a four...

    any bbs02/bbshd on freeride/dh bikes?

    I've got the bbs02 on a front suspension bike and ride pretty rough trails with it, that hill looks nothing special from my experience and I don't think a dh bike would be heavy enough to make much difference. Saying that I'm not a heavy bloke and I'm using a 32t front chainwheel and this combo...

    Bafang BBS02 750w off-roading and chain and gear set-ups

    Well I did take it out and had my longest off road ride so far (partially because once I had ridden the 3 or so miles to the tracks and got going on the bumpy bits I realised I hadn't locked my frame battery in place so had to ride back home to lock it with the key before it flies off) it...

    Bafang BBS02 750w off-roading and chain and gear set-ups

    I've yet to try it but last night I put the front derailer back on and removed my lowest gear from the rear and fitted a spacer behind the high gear to move the whole cassette out a touch. I realise a chain guide/ guard would help a lot as well as I higher quality rear derailer but right now my...

    Bafang BBS02 750w off-roading and chain and gear set-ups

    In the 180 miles I've covered since getting the kit a few weeks back I've dropped the chain more times than I can remember! Bloody 'ell...I tried losing a link but it made the chain so tight it actually got stuck on the high gear so after finally derailing it a had to put the link back in.

    Bafang BBS02 750w off-roading and chain and gear set-ups

    I'll try loosing a gear at the rear and putting a spacer in by the wheel, that should help and I'll also try reinstalling the front derailer. The 42t front sproket would be a really nice additions do if I read right it has a thick thin tooth setup to help grip the chain, if only I could afford...

    Bafang BBS02 750w off-roading and chain and gear set-ups

    I want to start a discussion about using the bafang mid drive on proper mountain bike trails and down hill/ jumps. I've knoticed there aren't many if any real off road riding vids on YouTube so I'd like to upload my own soon but right now the kits not up to it... A month or so ago I got bafang...

    [Solved] BBS02, C965 without wattmeter ?! PAS max 3 ?

    I'm pretty sure the bafang bbs02 750w weighs about 4.2kg not 6-7 and definitely not 10kg! http://www.eclipsebikes.com/bafang-8fun-bbs02-drive-750w-motor-p-1100.html?osCsid=c23aa4d1b79b3b20614cca22ec3156b2 I've just purchaced this kit from eclipse bikes and so far done about 40 miles on it...

    Increasing ah capacity.

    I don't want to buy any extra batteries for it for some time yet as its original ones still have a fair amount of life in them, at least enough for my 10 mile woodland ride. Lithium would be nice but can you imagine the cost of a 24v 70+ Ah lithium pack! Plus I'm not concerned about weight or...

    Increasing ah capacity.

    I have an off road mobility vehicle that runs off 2x 12v 73ah gel type batteries in series to deliver 24v to a single 40+ amp motor. Does a great job but uses a lot of power and the original batteries only really have about 27ah usable capacity Question I have is I've got a 12v 100ah deep cycle...

    Advice on full e-bike build for someone new to the field

    I'm assuming there is something I can do to wire my brakes to the controller but I'm not sure what a reed switch or hall sensor is right now lol, I'm sure I'll know soon enough. I'd love to have a go on one but I very much doubt I'd find someone close even though I live in a city of 500,000...

    Advice on full e-bike build for someone new to the field

    I've just been reading through the pond post on the bbs02 and I'm starting to see the mass off differing opinions on it. I also see your point ykick about the bike running off, that could be irritating and I'll just have to cross that bridge when It comes lol. I've got no idea what to expect but...

    Advice on full e-bike build for someone new to the field

    To be honest I'm still fairly unsure of how much power I need I don't think I need to travel as far as some do, 15 miles is an absolute maximum but the cycle does involve so pretty steep hills which I'll be tackling at around 5-7mph maximum. After looking more closely at the headway cells they...

    Advice on full e-bike build for someone new to the field

    Nice to hear some good feedback for the bbs02, I don't doubt if it's pushed too hard it will burn out but hopefully taking it steady on the motor will make it last. Looking on the eclipse web site they recommend using the headway cells for the 750w or above not the lithium ion 18650 cells.....I...

    Advice on full e-bike build for someone new to the field

    Thank you! Saved me a fortune there. I've noticed this forum has many very knowledgable people on it but many are in the U.S. So some UK support is much appreciated, as is the advise from the U.S. Before I put anyone off helping lol it's just sites to order from and regulations are more relevant...

    Advice on full e-bike build for someone new to the field

    Wow that's some impressive range! I wish I had less hills around here and could get away with a 250w. Tool wise I do quite a bit of motorbike mechanics and general mucking about so probably have what I need somewhere if not I'll buy off line I expect. Em3ev looks like a really good site and I...

    Advice on full e-bike build for someone new to the field

    Looking at the write up for the Xionda its claimed that a mid drive still should out perform the Xionda on steep hills, which is what I need it for. I live in Bristol, UK which is a very hilly city with hills of 30% gradient in places and the estate I cycle in is 450 feet above sea level and I...

    Advice on full e-bike build for someone new to the field

    I agree most mobility vehicles are pants but but this one pictured above really is closer to an e-bike than a scooter, I've done 40mph down a hill on it! Still I find its 350w motor useless for any kind of incline. It's torque I'm after really not power, the vehicle pictured below (also my dads)...

    Bafang 8fun pedal play

    Where do you feel it lacks power? Hill climbing or speed, what do you weigh? I ask as I'm looking into the kit at the moment.

    Advice on full e-bike build for someone new to the field

    Thanks, I better start trawling through and try to find some relevant to what I need. I suppose one of my main issues is I've never ridden an e-bike other than my dads mobility power trike which was basically a 350w hub motor on a bmx style front end attached to a manual wheelchair, great fun...
