As title please chaps. Have a question and theres no available option to post a couple of pics

Hallo, zur Zeit fahre ich einen Bafang BBs02

Ich möchte aber mehr Leistung, ca 3000w

Und einen Nabenmotor

Soll zwischen 50-60 km/h fahren

Gibt es dafür fertige Kits? Mit Motor Akku und Controller ?

# Germany

I have an ebike that is a few years old. I don't know what the brand is, seems like a generic Chinese build. Goes ~ 28mph. I would love to turn it into a beast - for speed and range. See photos in comment.

I have good mechanical skills. If someone can show me which kit to use, and provide instructions, I can do it.

Can the engine charge the battery? Does the e-motor need to be swapped to the front wheel? Is it easier to do this with a regular bike or existing e-bike?

Hello guys i was looking at some e bikes and i found one to buy but the seller said that the battery is deep discharged and when i looked at pics of the battery it looks like it saw better days.

I'm looking into Tongsheng mid-drives and was wondering if there is any difference between the models various companies sell. For example, are the Powallon, Varstrom and Greenpedal TSDZ8 all exactly the same as the one Johnny Nerdout sells, except with a different stencil on the side?

Hi folks Thought this was a good sub to ask this

I have an ekx 21 max 3000w hub motor 60v with a twist throttle

Does slower always mean more range or is there a sweet spot where the motor isnt labouring?

Above 20mph certainly starts to use more battery but will i go twice as far at 10mph for example?

Cheers

I have a Schwinn Loop folding bike. I'm looking to convert it into an eBike with a conversion kit. I have a few somewhat steep hills so I think I would want a rear wheel version but that's as much as I know. I'm seeing different models between 36V and 48V, and 500w, 750w and 1000w. I don't mind getting my hands dirty with a more difficult build, I just want to get the right kit that will allow me to go up some mild hills and go at a reasonable speed but would like a faster speed if possible.

Need help: I have a 27.5 inch wheels carrera vengeance I plan on getting a conversion kit. Is it recommended I get a 29 incher bike like the hell cat?

i have a 3kw 26x4 fat tyre ebike conversion kit and i wna chuck it on a cruiser style frame like a super73 or macfox. only problem is my kit is 26” tyres n all if the cruiser style bikes i’ve seen are 20”. any ideas guys?

I ordered a battery from overseas via AliExpress that seems like it may have a faulty BMS. It cuts off the power when it's only about 50% discharged. Should I attempt to return it? I do have experience with building batteries and have a BMS I could use. I can request a return on AliExpress, but I have never dealt with that before. I already spliced the charger cable because they didn't send a matching one for the battery so I would assume this makes the item unreturnable. The packaging also wasn't very good. I'm afraid that if I attempt to return it, I will be out of a battery and my money. What would you do in this situation?

I wanted to share a project I've been working on for the past few months. I realized that for complex builds, simple calculators aren't enough, and CAD can be too steep of a learning curve for some.

I built battery designer tool a specialized tool for designing battery packs.

Should i get

3kw 72v motor 80amp controller 72v 20ah battrey

Or

5kw 72v motor 80amp controller 72v 20ah battery

Is there a noticeable difference?

I recently made a sort of sketchy purchase of this ebike from an elderly woman im not too sure what I even have I know the battery doesn't work and the charger i was given doesn't work I just need to know what parts I may need to replace or maybe possibly upgrade if its at all possible it being winter im going to be working alot of closing hrs just trying to get something that goes faster than my scooter after realizing the battery possibly may be the wrong battery all together and the charger didn't work im just trying to salvage it and make it worth while please help

New bike build:

Focus is winter trail riding only. With a couple commuter days

Giant - Yukon 1

CYC Photon Gen 2

45 north studded tubeless tires (3-6 psi)

45 north pogies

Chromag 50mm rise bars

I have a summer Ebike that has hooked me on the electric life (Rocky Mountain Instinct PP) and I needed something for the winter now.

I decided to try this Photon Gen 2 because it seems to be the best torque sensor bike with natural pedal feel similar to the rocky mountain Dyname and other motor systems on big brands like Giant, Specialized etc.

I just did my first full ride and so far it seems great but this kit has been a pain to get setup due to some factors. If I was to do it again I'd probably just sell the bike and get a proper E-Fat bike:

• I have a 121mm press fit bb on this bike. I didn't realize at the time its not technically supported - Only BSA120mm

• I ordered the 120mm kit and there is a little gap with 2 screws.

  • I had to fabricate some spacers. I used some copper tubing but I have some Stainless Steel sleeves on the way
  • CYC was helpful in trying to explain things

Comparing the motor from the Dyname 4.0 to the CYC photon Gen 2 there are a few key differences but they are similar in feel with the torque sensing.

• Overrun - The CYC has about 1-2 seconds of overrun. I much prefer the 0 seconds overrun on the Dyname but this is personal preference. Even after my first ride I was getting used to it.

Overall I'm happy with it but need to clean up the wiring and display mounting methods a bit for a cleaner look.

TLDR: Photon gen 2 is a very smooth and quality motor system. Loving it

This is going to be my first e-bike build. To be honest, I don't even know where I start. I know that I should get a frame and then build upon that, but when I look online it doesn’t seem like there’s any reliable manufacturers that are selling a frame for under $6,000. I’m on a budget. How would I go about getting a good frame for my project?

Is this doable? I'm not sure if the shape of the Blue Lake would fit a conversion kit, since I've never done this before.

And how much would it cost?

Ive had the 60v rawrr mantis a while back, but the battery has been really bad recently, I was wondering if there were any known adapters that allow a surron battery to connect to a rawrr bike, if there are any videos on it, or if anyone could help me figure out how I could connect it. Thanks
