Custom Torque Arms Update

Got the quotes back and have decided to make the pieces myself, the cheapest was asking $275 for CAD and laser cutting the two pieces... uh... not happening!  

Not wanting people to think I'm completely off my rocker, I'm planning on installing a custom cut steel plate that will act as a reinforcement/torque arm and will fit into the recessed area in blue. It will be fastened utilizing the existing brake disk attachment. The other side will be done the same way, I've found an additional area where the plate can be bolted to the triangle there as well.

After working with some Fimo Clay and an Exacto Knife, I was able to mold a rough drawing for the two piece torque arms. I have submitted this via PDF to 3 different companies in the area, one which does laser cutting, the other two that use other means to create metal parts. I've requested 3/16" stainless steel for the material spec.

My Latest Batch of Goodies!

My latest batch of goodies just arrived in the post. Cycle Analyst Controller (w/2.11 Firmware), full grip throttle, brake inhibits and of course.. cruise control

New Controller Just Arrived!

Controller is a Crystalyte 24-72V 35A Immediate Start Brushless Analog Controller.



 

Freewheel Has Arrived - Quick item of note for us NOOBs..

Quick item of note for us NOOBs..

Crystalyte motors require an older 'freewheel' 7, 8, or 9 speed attachment. Today's newer bikes use a 'cassette' vs a freewheel which allows for individual sprocket changes (this is what my bike had) and so I have had to purchase a 9 speed freewheel that's compatible with the hub motor.

The Build Begins!

The day has finally come..

The build begins

Starting with the bike..

Downtube 9FS Dual Suspension Folder

 

After saving for little over a year I decided on the Crystalyte 5303. Some say I was nuts to even think about putting one on a 20" bike, and a folder non-the-less (not that I'm the first to do so, but I might be the first to use a 72V pack to power it)..

Just call me Mr. Nutty..

 

I was able to get the 2009 model with the disk brake attachment..

I went ahead and set it up with an a 7" disk vs a 6" to add to said motor, I think it looks pretty damn good!

 

I wanted to get a feel for the new motor, even before I was able to swap out the cassette and rubber.



 

Got the disk on..

I'll be damned if this thing isn't looking better and better

 

Finally got some rubber on the rim, she be looking mighty fine!

Eventually I plan on swapping out with some Maxis Hookworms, but for now this will do

 

After researching my options, I plan on going with a Ping battery pack rated at 72V 15ah, which according to Ping is going to be two 36V 15ah packs connected in series. Ping will provide two diodes which need to be added in the circuit to protect the BMS for each pack. Of course this is the most expensive part of the build, so I'll be on hiatus with my updates till I've been able to sock away enough funds to get these packs.

 

Till the next update my friends!
