53mph Raptor Build

I rearrange the battery setup and cleaned up the wiring. I'm happy with the headlight, so I'll make that to a permanent setup and soon wire it up the main battery pack.
I did get to fit a 42T chain ring with space to spare. I had to add a spacer to the chain guide and remove the chain ring guard.




Powerlab 8 hard at work






 
Did some riding on the trails last nite and the controller never reached 60C. Plenty of power on my 1st and 2nd speed settings(40% and 99% throttle). Looks like I found the proper settings for now(97A battery & 150A phase) with the 26" Crazy Bob's at 50 psi.
 
looking good, how do you like the crazy bob's" i been running fat franks and big apples and wear them out very fast
 
Bike tires don't last too long. But I have almost 600 miles on my Crazy bobs and they still look good. The front looks like new. I also have the Michelin Pilot sports that look like new after 1000 miles.
I'm gonna go with 19" moto wheel setup for the rear. I'll gain some mechanical torque and only lose about 1-2 mph from the top speed. Tires will last a long time and dont' have to worry about getting a flat. Changing the rear tire on this bike sucks bad. It's not a quick procedure.
 
So instead of going with the moto rear wheel, I swapped over to my old Michelin's tires that was on my EVG bike. Big difference in how much better they ride vs the Crazy Bob's. Less rolling resistance, hang lower in corners, I can power out of corners without fear and a little wider contact patch on the rear tire. The rear is 66 mm at its widest and 42 psi inflated. It's a bit lower pressure compared to the Crazy Bob's. I've decided to keep the Raptor on the streets for a while and just run my mid drive on the trails.



 
Got me some Tektro E-sub brakes. The calipers look well made, but these have small brake pads. The brake levers look like quality stuff. Maybe swap over to TRP 4 piston calipers with the brake levers. For now they'll sit in the "to do" box.






I'm pretty good at setting up brakes, but for the life of me, couldn't stop the brake brake squeal on the rear. I got tired of fighting with and just bought me this Hayes tool. After 2 minutes with this tool, I had quiet brakes again.

Those are nice looking tires. My bike wears them out fast too.
 
These tires have a bit over 1000 miles on them already and they still look like new. So far I only put 20 miles on them on this bike. I'll see how long they last on this heavier bike.
 
This is from my ride into work. I'm not missing the 21s lipo setup at all. 18s still has plenty of speed and acceleration.

I installed my old 300lbs Titanium spring. Bike rides lower and can lean a bit lower in turns. Nice and comfy on the road and the Michelin's roll smoother vs the Crazy Bob's.

I rode the Critical Mass last night too. There was one other eBike there besides mine. It was an OptiBike.
 
Finally got to install the monster Hayes 9.5" brake rotor. Waiting on new calipers to complete the brakes. I used the brake adapter used for the 9" rotor by Hayes and I added 12.5 mm spacers to make it work.


 
Those are the same screws that I used before on a similar sized rotor. I mostly use my regen brakes when I'm on the road.
 
Finally got around installing longer kickstand and reprogrammed it for street use only.

Time for some maintenance after reaching 1000 miles.

Retighten all the bolts around the bike.
Took out the Magura brakes and installed Tektro's.
I spread out the swing arm a bit so I can could install two more spacers so I can use the Qulbix brake adapter and 5 speed freewheel.
