Building a new Ebike

[_paralyzed_]

Too cool. Maybe get a front fender off an 80cc dirt bike? Yours is fine, I just think an mx one would look awesome.

Here's a pic of the group of mountain bikers I rode with last week. I was the only Ebiker ofcourse. They took 4 breaks or so and I was barely breaking a sweat. Was a fun technical ride. The leader of the group build up my front wheel and works at the Bike Barn near my house.

Well, I broke my front caliper. The brake caliper broke by the screw mouthing holes. I ordered a new brake and some other adapters to take the side stress off. I'll see how well it does before spending money on some better brakes.

I could if I actually got rid of my pedals all together and moved over to motor 19" wheel sets. That be so badass, but I would only have a one moto track to play on, which is about 20 miles away from me.

I installed my new bike seat assembly and tried out a new battery and phase current setting. Almost 11HP. Fun for offroad, but not so much for onroad.




My inner thighs don't rub anymore when pedaling with the new narrower bike seat assembly.

Definitely diggin' that bike.

Mike, Motoped was testing the cromotor on their bike. They are having big plans with their electric version.

Messed around with the bike today. Swapped shocks and springs along with a new brake mount for more clearance.





Swapping springs. New spring is 400lbs. Left spring is 300lbs Titanium, center is 350lbs and right spring is 400lbs.


I just hang the bike when I work on the shock or drive train.


Shaving off some material from the original mount wasn't enough.

So as goofy as it may sound, I do like to pedal my Raptor around. So I wanted some more gears for the longest and decided to tackle this mission. The cheapo Chinese freewheel is destroyed when taking it off. Just had it open up the side cover and lift the assembly off. Ball bearings all over the place. Screwed on a Maillard 5 speed freewheel, with 14T being the smallest gear. I can only use 4 out of the 5 gears. The derailleur rubs on the motor side cover in 5th gear.

I used a cutting bit, 2x4, Royal Purple motor oil, vice and a router for a poor man's machining job. I got the 255mm rotor installed on the rear.

I have really enjoyed watching your project from the start. You seem to be eliminating most of the problems that everyone runs into doing this sort of build. I really like the way things have turned out so far, and I cannot help wonder what your going to come up with next. Now that you have gotten this far I have to wonder how much you have invested into this bike? In other words what would it cost to put together a kit for a mirror build? I have wanted to build one of these, but the amount of time you have already put into figuring this thing out has been humongous. I could not imagine spending money building this bike and having it take two years or longer from start to finish. I can imagine picking up all of the pieces over a six months or so period and then diving in and building one ready to ride in a month.

Thanks for following my build. I've invested way too much. Gonna sell almost all my RC stuff to recoup some of the money.
Cost I'll have to add up soon. I can post cost for a variations of builds. I can also post various needed tools to make your life easier.
There is also a new controller I'm waiting for from Russia to be released.

It's amazing to think of some of the places this stuff comes from, and what you have to go through to acquire all of it. I have wanted one of these bikes for years, and if I have gotten started I would have done it the same way you have. Starting on the low to middle range and eventually would have ended up with something along the lines of what you have done here. I hate using crap parts just to save a few bucks, and being a perfectionist means that your never really done, because something new always come along that we just have to add. I am loving the way this project has turned out so far.

I have the option to go with moto 19" wheel setup. That is another money pit and pedaling would be totally pointless.
I was quoted a ridiculous 900 bucks for a complete schlumpf high speed drive.
Finding a badass dual disk brake setup for a MTB is still a challenge. I can find Pedicab setups for a high price. With that kind of money I would be better off with scooter brake caliper. But it wouldn't look as nice.

The controller that I want/need for max enjoyment among other things comes from Adaptto. It's a totally different animal.

It has a built BMS option, so you can use any battery chemistry you are comfortable with. All settings are changed through the dash unit. No PC needed. You can add the coil setup and charge through the controller as well. Makes for a stupid easy setup. It comes with a nice warranty. You can also buy the unlocked version, but that doesn't come with a warranty. The Max-E model I want is not available yet.




So basically I will be done after the controller and battery update.

[RC-Monster Mike]

Sounds like a cool controller - what voltage and current will it be capable of?

[snellemin]

I believe up to 100V in the unlocked version. But I won't be running that much as there is plenty of power on tap with the bigger fets vs what I'm running now.
Some forum members insisted on 150V max version and a small batch will be build if you want one.
