Electric bike conversion kit

[613]

Hi
I was sent here from the motored bikes forum and was told to ask you guys. I am looking for an electric bike conversion kit that includes everything that I will need including the battery. Or a good kit and a recommended battery to go with it. I want to get into electric bikes because I can’t take my motorized bike many places because it is to loud.
Thanks

First you need to know what you're looking for. IE: speed, range, comfort, riding style, terrain,

It's often cheaper and better to buy out right but again that depends on the desired end results.

I am looking for something I can cruise on so a good battery life, I would like at least 30-40mph but isn’t a dealbreaker, we have a lot of big hills around us. My motorized bike can go 38 so I want something that can somewhat keep up with it. I would be putting it on a men’s hybrid style bike.
Thanks for the help

Who could I talk to about this?
Thanks

Read here and other places and ask questions. The only dumb question is the one unasked... Youtube and such have lots of "review" videos. Often times paid for reviews so keep that in mind. List out the things you want then find a bike with good stats that fit your needs. Then it's just finding the right price.

Hello, you've got the right idea. eBikes enjoy a lot more freedom than gas bikes. 40 mph is doable, and 30 to 40 mile range isn't a big problem either, I used to build china girl motor bicycles, and I'm still a member of the Motorbicycling.com forum. I switched over to electric bicycles in 2013, and I've now built 7 of them. What I've learned is it's a lot better to start building on a factory eBike frame than a regular bicycle frame even if you have to buy a whole bike to do it. It's probably cheaper too, and the bike will be a lot more road worthy. There's basically 2 kinds of eBikes, the normie 28 mph bikes preferred by old geezers, and faster ones that young riders or, riders coming from motorcycle backgrounds prefer. This being your first eBike build I would recommend finding a fat tire bike as your donor bike. They're an easy platform to build on, and there's a lot low cost fatty'
s out there. A used one would be good for your purposes, new works too though.

You'll need 1500w to go 35 mph. 2000w will do about 40 in good conditions. Where I live you need at least 40 mph to stay alive on the street, but I usually build to about 6000w so that when I'm cruising at 40 it's less than top speed which helps your range out a lot. Running at top speed you're lucky if you get much more than 1 mile per amp hour, but if you can do 40 on 80% throttle it has very favorable effect on range. That's why it's nice to have more top speed potential than you need. When it comes to range, the number of watt hours is the most important factor.

I like to look around,so speed is no problem for me, there are a lot of options for 5 minute a mile ebikes.easy .,reliable,basically quiet. the big problem with fast aggressive bikes is the noise and focus,when you spend most of your time looking for whitetails and checking your six it pays to have the the ability to take in your surroundings. two things,be able to stop quickly and make it visible,too many 4 wheel drivers have"highway hypnosis 'as in"what was that bump?".

This is an example of the latest bike I bought to build on. It cost $1700 hundred shipped. Even in stock form you couldn't come close to building one like it for that price. Stock it's 1500w, 48v, 40 amp controller, 38 mph top speed, barely, and 30 to 40 mile range depending on how you ride. That's already fast enough for your purposes, but if you're like me you're not happy until you build it yourself. I rode it around stock for a couple of months before starting the build.
Now it has a 5000w motor running on 72v. The controller is 80 amp foc, and it tops out about 50 mph without resorting to foc. I built the battery, but 20 ah was the most I could fit in the stock shell, so my range is reduced a little. 1512 wh vs 1440 wh now.

I saved money by building on this bike rather than building from scratch because it already has a great frame, 4 piston brakes w 203mm rotors, and full lighting. The paint is stock. This how it looks now.

nice,however that thing is an ecycle,that much potential has many mopeds beat!

If I were to start with a factory ebike that I could build what would you recommend?
Thanks

I have only one ebike ‘build’, really a bike assembly, under my belt. I had assembled a non ebike mtn bike circa 2005, then last year converted that bike to an ebike with a Bafang BBSHD kit. It is a 52-volt motor, but, dumb me, I bought a 48-volt battery thinking it would be better for the motor. That was before I discovered this group and read how sturdy the BBSHD can be. It is a great motor for my torquey needs. When I first got it together I went up to 30 mph but with me pedaling. For the speeds you want to sustain, maybe consider a CYC X1 Pro. There are many comparison guides out there, here is one:

Super 73 are popular eBikes to build on, but a little over priced. Used ones should be easy to find, there's lots of less expensive clones to choose from too. Do a youtube search on 3000w or 5000w ebike builds, and I think you'll get enough good ideas to start formulating a plan.

start with the best go from there..
cyc including battery ..IDR their battery specs

the bike you want will soon be illegal everywhere,and it will hurt ebiking everywhere,laws have a tendency to lump anything that seems remotely the same together,witness that fiasco in Florida,where the kids on escooters got a blanket ban on ebikes in general,why do you need so much speed? do you even wear a Helmut? Darwin or the wheelchair awaits,bur YMMV!
