Hi I’m looking to make a light with a switch hooked on that runs off it’s own battery pack and not the main one, I have the battery holder/discharging device and the light bar, will be getting some 3D printed mounts made however I’m looking to put the switch on but haven’t a clue how to go about...

Yes the battery mount, my controller supports both 48V and 52V I’m just wondering if there is something inside the mount which is for a certain V and could cause an issue by using a 52V on the 48V’s mount or vice versa

Might sound like abit of a stupid question but I know these battery’s can be no joke if something does happen, I have a 48V and 52V battery with same docking stations and wondered if I can just slide it off and on with 1 of the docks and nothing bad will happen in result to the docking station...

Hi I recently had a problem of a reverse back wheel so I cut off the 9 pin head and replaced all cable heads with gold bullet connectors, now I’ve got it running forwards and it free spins when I lift it fine, however when I sit on the bike and throttle it makes a weird noise (sounds like a...

Nothing in the manual about the sw900 display settings and when I googled it, it says p15 isn’t implemented and on my CSC wheel on p15 u can’t change anything up or down, also the 50kph/hr ( for max speed no limit ) setting goes to 100 kph/hr

I’ve tried disconnecting a reconnecting in multiple states of being on and off, I heard you have to peddle it forward while turning battery on as learning wires will sort of learn from this and fix it but I don’t think it being pushed into reverse with me peddling it the other way wouldn’t be...

Hi I’ve recently just bought a voilamart 1000w 48V with waterproof connectors, I came to a stop and went into the shop after returning and getting back on my bike I flicked the on switch and tried to go forwards, upon doing so when I tried to throttle the motor was pushing my in reverse, I know...

I’ve bought the diy e bike kit and upon looking through the manual it says I can change the wheel diameter, it is a 29” wheel however it’s came preset as a 26” and I’ve left it as it is since it’s running smoothly and I know I should probably change it up but will it increase my speed or just...

Hi I was wondering what measures I could take for layers of security to keeping my wheel on? (1000W 48V rear motor) I have already got myself a torque arm but was wondering if there is anything else which can completely just make it feel like nothing will go wrong? I overthink sometimes and if I...

I was under the impression I am going to be extending the dropout to make it deeper so that the wheel fits in to the dropouts more? Can someone explain what to do when filing please :D

Hi I have recently learnt I need to file my rear dropout, I went and bought a round file that fits in since all my others didn’t, is there anything I should know before I start to file it down? I would like pictures of failed/perfect filed ones if u can (please list failed/perfect if u can show...

Ah I see, thanks for the advice bud also I have a carrera hellcat with the dropout a size of 65mm, I’ve noticed the bafang will install to 68-73mm dropouts, is it possible to modify the dropout to a bigger size to fit the motor or would I have to use a different frame? I’ve been looking on a...

Ah I see, seems you know your stuff, is there any parts in which I can take note of which would be the best to use when using a bbs02 kit? I don’t wanna keep having troubles and you seem like you would know the important things for doing an installation going smoothly, is there any videos or...

Hi, I’ve been dabbling around looking for frames with the right size dropout for fitting a bafang mid drive 750W and was wondering if there is any bikes out there cheap-medium expensive range which will fit the bafang on perfect and still give me a nice ride, I don’t want a super cheap bike...

I found this linked to the hub I bought, does number 4 mean it needs to be that size down in the dropout for it to work best

so if I file it down it should rest in nicer obviously, will this solve the problem of it coming out? I watched a fair amount of installing videos and looked around for everything and thought it would be easy but I haven’t seen any video or anything telling me about the drop out needing filing...

Hi I’m new to building e bike conversion kits and I’ve had a few problems with the rear 1000W hub wheel coming from the axle, I currently have 1 torque arm fitted which has been successful to stop the wheel from spinning so luckily I can still use this kit as no real damage has been done to...
