Those front wheels come in the frame kit. You can contact utahtrikes they'll sell you the double wall wheels.

NEW TORQUE ARMS !!!

I designed these myself and got them made for 10mm axles. I used to have a thick washer but the HS3540 on a 20" messed it up so I made these.

They are 3/8" A36 steel and I'm gonna put em to the test.

This nice torque arms designed!

I was buy torque arms from ebay usa - http://www.ebay.co.uk/itm/Electric-Bike-Shorty-Design-Universal-E-Bike-Torque-Arm-Excellent-for-Rear-hubs-/281098483160?pt=US_Bicycles_Frames&hash=item4172c675d8

Good stuff!. I live that trike looks pretty clean. You must be getting a good range since that 350w more on a small wheel must be really efficient.

Where are you from?

Yeah your trike look great i like its!

I where from live in UK but that say 36V 250W on road legal UK and 15.5mph speed UK... not 350W , So I think 350W to 500W can on road legal USA.

My KMX E-Trike 36V 250W full speed is 21mph - no load. If think 24 inch rear wheel will more up max speed

What happened to your original torque arms from doc bass? I'm building a KMX with the 1500W leafbike motor that neptronix reviewed recently and was planning on ordering a pair of his torque arms but if they don't work on the KMX then I would make my own.

Updated now with a video

No editing at all , no music. 808 v2 #16 camera mounted on giro remedy cam

The next one will have a cool intro and music.

just watched the vid': thxs for sharing, I saw you pedaling twice, once at 3:13 and once at 6:42, I assume the car we see at 3:13 is a police car and this was your motivation to pedal anyway, I guess a fairing would help hiding that you don't pedal that thing :wink:

Yup it got to me ... as much as I tried holding back on this I HAD to order me a trike kit from utah trikes.

Took the hint from andrew.box and ordered a frame kit with double wall rims (20") on the front. I think it is better this way but I'll end up buying the brakes I want and components I want.

Bought a crystalite HS3540 from method's like 3 weeks ago on a 20" rim.

My plan is to run this thing @ 20S lipo or maybe 18S lipo still trying to figure out which one.

I bought the controller a while ago and it is being modified by amberwolf to handle more current and bigger phase and battery wires. Fets are going to be replaced too.

I'm working on a 24S a123 monster battery for this thing but in the meantime I would like to start with 3 6S bricks from hobbyking for easy hookup and testing.

My question is this;
do you think 3 of these in series might work well pulling 60-70 amps max from the battery
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=21431
I'm not looking to break 50mph with this motor or anything but to have a constant 30mph with bursts of a bit more when needed. If I crave more speed I'll probably add another 6S brick for 88.8V but for now I think 3 will do.

Another thing I want is to be able to fast charge this thing.
Are these nanotech's really good for charging at 2-3C?

Any suggestions in terms of brake and other components I might need. I was thinking AVID BB7's on the front (200mm) with a dual pull lever. Hookworms in the back but have not settled on what tire to use for the fronts.



UPDATE Oct 6,2012

Well some updates and pictures as promised...

Prepping the HS3540 and front 20" rims

Front disc brakes and spindles attached plus tubes and tires

Frame is out of the box to be prepped for the torque arm installation using the DP420

Front left wheel installed

Both front wheels installed

Seat installed too

Added the freewheel to the HS3540, had to make a spacer out of a washer I had

Some bonus pics

The torque arm I left curing with a heat gun and a carton box @150F for about an hour. Thing is solid now



Still to do;

Install the front brake cables and adjust accordingly
Install crank and pedals
Install chain and rear derailleur with shifter

Lots and lots more....




UPDATE Oct 13,2012

It is running now .... not electric at the moment but everything else runs fine. I'm gonna tweak the brakes and add the shifter cable.

UPDATE Oct 17,2012

Installed the shifter for the rear derailleur. Bought an SRAM grip shifter and cut a wuxing handlebar grip. 7 speeds it is. Now I need to tension the rear chain a bit since it is a bit loose. It still shifts good but i'D like to tension it a bit.

Shifter and Brake

Installed a CA up front and used all the cable routing stops for the front derailleur that I won't have.

CA with a bit of clearance on the right

Left clearance

Now onto the throttle ... I bought a throttle from an user here on ES a while ago. Now I got it installed YPEDAL's style. Definitely the best way to install a throttle on these KMX trikes.

UPDATE Nov 17,2012

Well as promised here is all the updated pics of what I think is my new commuter in combination with my idrive. Enjoy!

And RIDE STATS
NO REGEN
LOTS OF START AND GO PULLS
NO PEDALLING
