I did link it in the original post, but I tried to be all clever and hid it in the word ‘this’, so you may not have noticed it! (It’s here https://www.bike-discount.de/en/buy/cube-elly-cruise-easy-entry-frame-pistachio-n-blue-840128) I have a hailong case, so it’s sort of long and thin. So even if it is mounted ‘high’ on the downtube, a lot of the weight will be low down, and it will still be a lot lower than a rack mount battery I’m really not too bothered about kicking it, just about safety and whether the frame can take the weight. It’s basically the only option if I want a big bag on the rear rack anyway

I was using a step through because I wanted to have a rack with quote a tall bag on the bag, so I wouldn't be able to swing my leg over, or have anywhere else to put the battery. If the battery is mounted fairly high up it shouldn't be too much in the way (and I only have size 8's anyway!), but it will definitely be easier than leaning the bike over and trying to thread my foot over a top tube. I though the same thing, although even a fairly light battery is 3x the weight of a large water bottle.. The frame I linked has the bottle mounts quite high up anyway, so it should be fairly out of the way. I did have a look, but it would be too short for my battery.

Bought this frame to build a new bike, but now it's here I've started to worry about whether it's a good idea to mount the battery on the downtube? A step through frame is already less structurally sound than a diamond frame, and electric bikes with step through frames always seem to have the battery on a rack at the back. I guess this could be because it could get in the way when mounting the bike or something.. Has anyone done this and had it go ok? I found this thread, don't know whether he went through with it in the end

Oh yes, maybe that is a consideration I've overlooked. Although is that mainly a performance thing? This will only be powering a BBS01, so I'm more concerned about safety and longevity

Could anyone share their experience with Enerprof batteries (or even better, their ebay store)? Specifically the quality of the thing and how its held up over time? Or failing that, any recommendations for battery sellers on eBay? I need a new (48v) one, and there's 10% off on eBay until midnight!

Yeh convert probably wasn’t the best word I just meant I currently have a normal men’s frame with a BBS01b that I installed myself, and I’d like to swap the frame for a step through one but I don't know where to find one

I'd really like to convert my ebike to a step through frame, does anyone know where I could find one? I've been looking on ebay, but having trouble finding one with horizontal dropouts, disc brake mounts, and preferably a battery cage behind the seat tube. Bike stores seem to just have road and mountain bike frames. Does anyone know where shops that sell pre-built ebikes get their frames from?

Oh wow, that's a fantastic resource thank you! Don't know how I didn't find it before One more thing though, which I couldn't find in that faq (although I've only skimmed it atm) - how much resistance should there be when rotating the pedals with the motor off? I read that there is a clutch of some sort between the pedals and the motor, so I thought it should be fairly easy to turn. Maybe not like a proper bb, but similar. But mine is, not exactly stiff, but not loose either. For instance, if turned to horizontal (with no chain attached) gravity is not enough to turn it vertical. There is a fair bit less resistance when pedaling backward however, and gravity is enough to rotate it in this direction.

Ah yes! Checking the grounds is a great idea, thank you And thanks Nealh, I assumed those were the wire assignments, but it's good to have it confirmed. Assuming it works fine, is there any preventative maintenance I should perform before fitting it to the bike, such as greasing gears or waterproofing? I know the 'B' version was supposed to have improved waterproofing, and I will definitely be using this in some heavy rain.

Bought this BBS01 from eBay the other day because it was cheap. I want to test it just to make sure it's working, but I don't know what the polarity of the battery connector is (I presume that's the two pin one at the bottom in the photo..) Would anyone be able to help me figure it out? I could cut into the wiring, but a) even if the wires are red and black I couldn't be sure they didn't just mix up the colours, and b) it would make it more difficult to return if it didn't work I'm thinking I might have to disassemble the housing to follow the wires inside? But I'm worried that would involve disturbing some sealant or something

Oh yes, right you are - I'll ask Woosh whether a new controller could work with my hub motor, otherwise I'll have to swap the controller over to the new rack. So the battery will still come with rack and charger, but the rack will not include a controller

Recently bought an XF08c kit from Woosh bikes with a 13AH battery, but am starting to think I should have bought a larger capacity one. So I’m gauging interest in this before I commit to a new one. I’ve had it about a month, used it for 260 miles, and it has approximately 12 full charge cycles on it. It will come with the charger, rack, fittings and both keys. Price is £250, which is £70 off of the new price from Woosh, but I’m open to offers.

Thank you for this information, but can I ask why I haven't been given any of it before now, despite buying a kit? It's not in the manual on your website either.. Unless I'm missing something? I'm particularly worried about how you've said that #4 is very important, yet this is the first I've heard of it; is there anything else of similar importance that I should know? It wasn't so much that the rotor wasn't lining up with the caliper, more than it was fouling the carrier. One last thing - do I need to have the black plastic spacer between the rotor and the motor? If so I really don't think it's going to fit..

Yeh it's definitely an alignment issue, which I think is why I was confused about the caliper adaptor suggestions. I've tried it with a spacer and it works (stretching the frame slightly), but that was also with one of the cogs from the cassette removed. It's an aluminium frame (7005 alloy) rather than steel, and everything I've read suggests you really shouldn't stretch aluminium.. but we are only talking 1-2mm so I'm guessing it will be ok? So my plan is to find the thinnest washer that will stop the disc rubbing on the carrier, and also to file the dropout on the cassette side so that it will fit with all the cogs Thank you for all the replies, and if any of that sounds stupid/dangerous please let me know!

Was that in conjunction with mounting the carrier on the outside of the frame? Because otherwise I can’t quite imagine how that could solve the problem of the carrier not fitting between the disc and the frame...

As per title, I received the XF08c kit today, but I can't get my caliper/carrier combination to fit With the standard mounting (caliper on the inside of the dropout) the carrier fouls the motor, but even if it didn't it would put the caliper way past the brake disc I thought of mounting the carrier on the outside of the dropouts, but this leaves the caliper sitting right underneath the frame so that's not going to work either It was already a tight fit between the dropouts so I don't think I can put spacers on the inside to make a bit more room either, at least not without stretching the frame which I imagine would damage it? So am I missing something, or is there something that can be done?

So what specifications did you look at to arrive at that conclusion, considering on paper the Suntour HESC has a higher torque rating than the XF08C? Like what should I be taking into consideration when making these comparisons? Are you saying that the current changes the rated torque? I understand if that question requires too complex an answer! Happy to just be given a link or a search term

So given that that would be 10-20% less torque than the one I rode today (plus my bikes larger wheels), should I expect that to give 10-20% less assistance up the hill? If so I'm not sure that would be powerful enough.. Or are there other statistics that I should be considering?

Thanks for the reply, I was going to phone you guys tomorrow anyway Do you have the torque rating for that motor or any of the others on your website though? Or is torque a good way of finding something as powerful as the Vulcan I test rode today?

I started a thread the other day about finding a suitable kit to help me get up a particular hill in my town. Someone in that thread suggested getting a test ride from Halfords so I could see how it dealt with this specific hill. I did that today and it felt like exactly the level of assistance I was looking for, so I would like to buy a kit of the same power so I know it will definitely be good enough. The bike was a Carerra Vulcan with a Suntour HESC rear hub, which according to their website kicks out 50nm of torque. From my research the XF07 that I was looking at is more like 30nm which, along with my bike having slightly larger wheels than the Carerra, leaves me thinking it won't be enough. Does anyone have any advice on any other hub kits (or mid drives, but they'd have to be below £550 inc battery) that have that kind of torque? Or is torque actually the spec I should be focussing on?

Damn, guess I will have to get pas and screen then - turning it on just for the hills does seem like a good compromise I'm 30 and am definitely physically able to get up the hill, but unfortunately I seem to have the lower back of an 80 year old and so need a way to get up without too much strain. The hill in question is Penglais hill in Aberystwyth, which does seem to be a bit steeper than yours (12% compared to 8%), but I don't know what affect two people have on the effectiveness of the motor. I guess I'll be phoning Woosh tomorrow to ask their advice, thank you for all the replies Btw, I don't suppose anyone knows the torque ratings for the Cyclotricity motor (or the model number) or the Woosh XF07?

Oh interesting, I wasn't aware of that. I think I won't worry about it for the short term since I really need to get something ASAP, but I will definitely try and find a way to make it legal once it's all set up. Maybe there exists some kind of throtlle cut off if the pedals aren't turning? I really don't want PAS This sounds promising, could you tell me the grades of the hills you've used it on? Or where they are on a map so I can work it out? About 75kg, bike's about 15kg inc lock, and then I have my Deliveroo bag which varies from maybe 3-7kg?

Hi, I work for a Deliveroo, and I deliver in a town where the student campus is on top of a big hill. I have a bad back and I can only go up that hill 2 or 3 times before it gets painful, so I'm looking for an ebike kit that will help make this big hill feel more like a small hill (I'm about 75kg). I'm not looking for something to whizz me up without any effort (I like that my job makes me exercise!) and I will only be using it on the hill and nowhere else. The hill is half a mile long and about 11-12% gradient; I go up it max 8 times per shift I'm looking for the cheapest and simplest kit that meets these requirements, but I would like it to be from a UK company for both speed of delivery and warranty purposes. I think I've decided on a front hub motor due to ease of installation and price, I think this should give me the level of assistance I'm looking for (but please let me know if I'm wrong!). I would also like a bottle battery for simple mounting and just a simple throttle, no PAS or LED screens etc. I know a mid drive is preferable for hill climbing, but they are more expensive, harder to install and from what I've gathered you lose your front deraiulleur which, since I want to ride my bike normally everywhere other than this hill, would be too big a disadvantage. These are my thoughts on the options I’ve found so far, please let me know if I’ve missed any Panda pro 250w kit Read some bad things about their customer service, although it seems to have mostly been last year. However the lack of a phone number on their website doesn't reassure me. Kit doesn't come with a throtttle, and ones on their website are out of stock (don't know if if other throttles will be compatible?) Cyclotricty 250w kit Again, read some stuff about bad customer service, also read that it doesn't come with a charger? Powerbikes sell this kit and it comes out cheaper with a bottle battery, I've also read good things about their customer service, however there’s no mention of warranty on their website? woosh 25" XF07 Read good things about customer service, comes with throttle and bottle battery, but more expensive. I don't think this is due to bad value, just that it comes with more than I need Any advice or corrections appreciated, thank you!
