Used what we had

Well I had this 1500 watt rear hub wheel laying around( the rim was pretty narrow so I put a 26x 2.1 knobby on it, it went on the back of the 27.5 fairly easy, that's when the head-scratching and "rigging" begin, the donor bike had rim brakes and it seems that they will not touch the new rim, this thing does seem to have a lot of power and I am wondering how to get some brakes on the back wheel, the front has a disk brake setup, any suggestions?
 
Hi kmc,

I've a 1500 watt hub drive ebike sitting in my kitchen i ride quite a bit.
Just got done building a Luna BBSHD with the off road programming that I intend to ride tomorrow if it's warm enough.
Also have a Specialized Sirrus with a 750 watt bbs02 that i mainly use when i want to exercise.

If you need any shop talk or assistance feel free to contact me here and i'll give you my phone number.

With that 1500w hub drive you're going to need a good battery, i use 52v 35ah BTRpower battery for that one, they are expensive those batteries for these things.

Ride Safe! :cool:

Is the 1500w hub motor set up for a rotor? if so it might be pretty easy to get a rear disc brake adapter.
I've used them twice on gas bike builds.
Anyway i live in the same town you do i think, so send me a msg if you need any assistance :)

Ride Safe!:cool:

Ok, my number is 540-996-4165, right now it just has a little triangle battery feeding it, will probably parallel a higher amperage battery to it, right now its just proof of concept, I going to gift it to my brother who for some reason wanted a good bit of power,I opened the throttle on it it tried to leap forward with a good bit of force,I believe I am headed in the right direction, thanks for the tip I will see what I can find in the adapter line, the motor has the six screws-Kevin
 
As long as you can mount a rotor on the the motor all you need now is a rear disc brake adapter.
I have one in the living room that you can have if you'd like to try that route.
 
heck i might even have a couple rear mechanical disc brake systems you can have.
i have so much stuff just laying around it's nuts LOL

I appreciate that, theres not much room on the chainstay I maybe can mount something horizontal. I will pay the postage if you want send the adapter-Kevin

Well the "Mullet" is up and running, looks pretty good, the triangle battery is working alright( 5 miles still showing full) also its right strong,nephew got the sw 900 to show mph and after the first runs it hit 25-26 mph no problem( yes there is a problem- the brakes suck) we have decided not to try for any more speed, when the battery was fresher it hit 50 kph, we have unanimously decided to not run that thing anywhere near that fast, it needs lights and better brakes, to be frank I was surprised at the performance of the 1500 DD it seems to pull pretty good too, after nephews thrashing the motor was barely warm.
I generously donated this setup to my younger brother( He is aware of its safety concerns) -I have an adapter coming for the rear disc brake conversion-should I use the 203 mm disc I have? The good thing about all of this is it got two mechanically and electronically minded People interested in EBikes, they work for the phone company installing fiber optic and networks.

oh man that is great :)
ok the SW900 has some settings to fine tune things a bit. I have them written down i'll look for them and send them to you in msg.

Sure use what ya got ;)
and a 180 for ther rear works great, i have 200mm front 180 rear on the new BBSHD build.

Sounds like you got it together then Kmc :)


Enjoy & Ride Safe! :cool:

rode the lunacycle bbshd off road programed for 21 miles today, from 57.5v down to 48v
could have prolly gotten another few miles out of it i guess. the power was nuts man lol
 
Lunacycle BBSHD 1600W with added Ludicris V2 controller.
Added the eggrider V2 display to be able to set deeper parameters.

60v 45ah battery seems to do pretty well so far cant wait til spring gets here! :)

This thing is a torque monster. Have the settings based upon others settings and amended a bit to get more range than power, but damn, this thing is nutty torquey!
 
Better not get that back wheel in a "stalled" position you may be walking home( that monster is a "motorbike!")
 
Yes sir lets pray that never happens :)
Rode today from staunton to middlebrook and back then out to verona and back, so
about 30 miles total with a few rides around the park.

How are your builds going? Has your brother gotten any ride time and what does he think?
 
Yep, He likes it very much I am surprised at how well the small triangle battery holds on( must have been good cells) He is having a time getting some good brakes on the back.I believe He said it has hit 26 mph on throttle, His son likes it too. We had an older build returned ,a trek Antelope, it has a 36 volt 20 ah battery,I managed to shoehorn everything into a plastic Harbor Freight Ammo box on the rear rack, it climbs well with the throttle assisting the rider's output, with no suspension it has a lot cleaner look,I may contemplate installing a pedal-assist setup on it.
My real hope in all this is to generate interest around here for the EBike phenomenon, thanks for asking. I do not want anymore 20x4" bikes because the last one I had would go 32 mph on throttle or assist and it really felt unstable, it had thrown Me at least once and I was lucky it was at low speed.
If we get everything working and cleaned up I will try to post some pictures, How's your bike do on "Sears Hill"?

oh man i'm glad yur alright. well the 1500watt hub drive pulls sears hill from 25mph it slows down to 19mph by the time i hit the top of the hill.
I havent taken the BBSHD mid drive up sears yet, but i'd bet it'd pull up sears better than my hub drive ;)

my hub drive has no pedal assist....all throttle lol but quite enjoyable. my mid drive has a throttle but i never use it i stay in PAS 1 mainly. Then i have bumped
up to PAS 2 and 3, i just never stay in them higher PAS levels very long time.

Well if ya ever see me riding around town stop me and we'll have a coffee and chat a bit :)

Ride Safe! :cool:
