BE-Bike - The project starts NOW - Turnigy 130KV Brushless

Hi Guys!

A few months ago I made a topic at endless-sphere about converting my mountainbike to electric, I got very helpful reply's from members of this forum (thank you! especially: Aussiejester, Thud and sona1111). Today I turned 17, and I finally bought some stuff at Hobbycity for my MTB. (I actually bought a present for myself lol) The MTB I'll convert is a little old and rusty, but I think it will be OK. Some old pics of this rusty thing (I'll disassemble all the parts, clean etc. them and then re-build the bike before I'll convert it):




Now to the things I just bought at Hobbycity (a total of $480 :o ):
- Turnigy 80-100-B 130Kv Brushless Outrunner (I know, overkill )
- 2* ZIPPY Flightmax 5000mAh 5S1P 30C
- iCharger 3010B 1000W 10s Balance/Charger I'm very curious about how this thing will perform, at this moment I've got a cheapo 50Watt charger
- Turnigy Servo tester
- Turnigy HV UBEC (8-42V)
- Some small things like connectors, ball bearings, thread locker and some other things for my RC's



Things I still have to buy:
- Castle Creations ICE HV 120A ESC
- Gears, shafts, aluminium, caps etc.



I'll only use 2* 5Ah 5S 30C LiPo's in series, but gear the bike down to about 35MPH to get the current down. As reduction unit I'll try to make something like Mud2005 at Endless has:
http://www.endless-sphere.com/forums...e.php?id=31041, a belt driven system from motor to a shaft, then a chain driven system on the other side of the shaft.
3 questions about this:
- Where to get a hardened shaft?
- Where to get the 'belt drive system'; a small 12mm inside dia. gear, a big gear and a belt? (Sorry my English isn't that good, I don't know the name of the parts)
- Where to get a freewheel + sprocket that will fit the hardened shaft?
I'm still not sure how the sprocket/freewheel on the shaft will drive the rest of the bike as I want to be able to paddle too.



I'll keep you guys updated... :)


Oh, and for you who want to know why I'm calling it the BE-Bike: as you see I bought the first things on my birthday, so it's a Birthday Electric Bike I know that doesn't makes sense lol

Now I'll enjoy the last 4 minutes of my birthday hehe (It's 23:56 over here)

What power supply are you going to use for the 3010B iCharger? I am interested in getting that model myself, but my current power supply definitely would need to be upgraded too.

No disk brakes, this is an outrage.



Just Kidding, this is a stellar project, one that I wish to perform in the future.

I'll only use a 12V 500Watt PC power supply (I got it today, I have to convert it), as 500Watt is enough for the coming years. Maybe I'll get a 1000+W power supply in the future, but for now it is not necessary.

Maybe I'll buy some in the future (these things are very expensive imo), but for now I'll keep the normal brakes.

pc power supplys are rated with all channels driven, the 12v rail is only a portion of the 500watts

Jup. My power supply is 800Watt and the 12v rail is idd 500Watt.

No way, first he finishes the LST 1.5 and now he's starting the e-bike which he has been jabbering about for so long and spends a ton of cash, I like the new you :D

Again on here: Happy B-Day!

Ooh lala, this should be funy.
Dang, a $400 birthday present?

Any progress on this build?

Metal! You actually were my first inspiration for this E-Bike


There isn't much progress, I ordered a bunch of things but I haven't got anything yet. Only one item (the LiPo's) has to get in stock at Hobbycity before the whole order gets shipped, hopefully it won't take too long. I also ordered a ENO freewheel ($80), an adapter from a member of Endless-Sphere ($20) and some caps ($10) for the ESC.

I've decided to go with a Castle Creations ICE HV 160. I want to buy it at Towerhobbies as I get a nice discount over there but they have only got the Lite version. I e-mailed them yesterday if they get the normal one in stock, no answer yet...

Awesome! I have almost 600mi on my bike now and I'm getting to really dislike the hub setup. This fall/winter I want to get a new bike, re-use the controller/batteries but use an outrunner. The hub motor is really heavy and it doesn't agree with the gravel roads I ride on.

You have a really nice bike to build off of! I'll be keeping watch on this thread!

[JAILBIRD]

This is a cool project. One of the guys has a converted mtn. bike at my LHS. He was saying he has something like 600mi on it, using a hub style motor. He has been having problems with broken spokes. I'm not sure if that is poor maintainence though.

I have a line on a Honda Rucus scooter with a bad motor for a BL project. We'll have to see it that pans out though. I'll be watching this.

Do you two know each other?

Update!


Today I FINALLY (it took 1,5 month....) got my HC package! Some pics of the items from the HC package and some other ones I got a few days before:


ENO 16T Freewheel



Paint! Correct: the bike will be Black, Green and Pink!



Adapter for the ENO freewheel with 1/2" bore



The awesome package that came today from HC! 1000Watt charger, 2* 5S LiPo's, 8mm Bullet connectors, UBEC, Servo tester and the...... MEGAHUGEMEGAMONSTER Motor! This motor is sooooooooooooooo huge, big and heavy! Totally awesome!



My sexy hand + XXXXXL motor



My Rustler and the XXXXXXXL motor!



Some other brushless motors and again the XXXL motor

[Metallover]

Awesome! Can't wait to see it come together!

I am a little worried about your range.. My 666wh pack get me 15-25mi, and you have a 185wh pack.. I'd guesstimate you'll only get about 4mi (6km) when riding hard and probably 7mi (11km) when taking it easy and pedaling..
