Went pedaling the bike today. It feels like you are moving a monster around. Installed the front Magura brake today and had to go with the 203mm rotor. Made a cut on the top tube for the CA. Been a while since I used my dremel and files.
So far no progress on the Raptor. I was rebuilding my EVG bike instead. I'm heaving extension wires coming in today or tomorrow for the magura brakes. I found out that those magic shine extension cables have the correct connectors for the brake cutoff.
I almost finished the bike. Still to clean up the install, wire up the brake cutoff and mess around with the CA.
The test ride was nuts!! Cromotor is a beast. Torque is insane when I went offroading a bit and the 3 speed came in handy. The throttle control coming off the CA is pretty good. The bike handled nicely, but will get better once tweaked. Pedaling was a PITA with the bike seat in place. If the bracket was slimmer from the top, my legs would not hit it. I'm putting back the moto seat.
I decided the put the controller inside the bike to keep the mud off from it. Still have plenty of space for the batteries.
The cromotor is just super quiet with Zombies 18fet controller. Gonna have to ask him what his default settings are.
The new swing arm is on the left. Notice the shock mount.
I put the motor seat back on. Blew my sensored controller, so I stuck a spare sensorless Lyen 18 fet controller in there. Not as smooth, but as powerful. CA recorded 55A max and I only used regen from 30mph and a phase gave out.
I've been riding with the Lyen sensorless controller and it works very well with the Cromotor. I'm 188lbs + bike 107lbs and the controller has no problem pushing me offroad. There is one some big dips/bowls that I won't try with the sensorless controller. Either today or tomorrow I'll hit the trails again with Lyn sensored controller and see if I'm brave enough to try those big bowls. I met these Japanese people on the trails and they loved the bike. One guy couldn't stop smiling after a test ride. Another guy thought he could keep up with me with his 29'er. :lol:
I added some more copper on the traces of Lyen 18 fet sensored controller as I did with the sensorless version. The controller is a bit better at the topend and climbing steep hills from a standstill. Sadly no video. I managed a speed of 46.8mph. Bike feels like it can go faster. I'll have to find out what that limit is one day.
I had my friend and his daughter ride the Raptor too. They loved it. He is about 265lbs and the bike still pulled him like mad. His daughter is about 115lbs and the bike takes off like a bullet with her on it.
I just added more copper like on the zombie controller. Makes a difference in the feel of the controller. In my case I saw a gain of 300-400W without changing anything else and going up the same hill. When I saw that I just upped the battery amp to 70. When the weather gets warmer, I'll most likely go to 75A battery and 150 phase. I'm using 3M Thermally Conductive Adhesive between the frame and bottom of the controller. I'll be adding a temp sensor on the controller in the summer to keep an eye on things. Lyen did state that his 18fet is rated for 5200W. Obviously I'm pushing more than that. I found that the 2.5x multiplier doesn't really apply on every bike. Total weight and motor choice effects what phase multiplier works best.
One of these days I'll send in Zombies controller for repairs. I really liked his controller when it worked.
I swapped over to Schwalbe Crazy bob tires for some onroad fun. Well I hit 53mp and the bike just felt stable. Regen brakes got a work out too.
Got me some bigger platform pedals too and they feel better with this big heavy bike.
I had to add a spacer to the front brake rotor for some more caliper clearance.
It's just a shock cover that I made using two Lizard Skins Neoprene shock covers. Keeps the mud off nicely.
I have yet to send the blown controller back for repair. I was just running 21S, activated regen and blew a phase. I could run 24S, but I might be pushing the controller too hard with the cromotor at that speed. I could try it, with reducing the phase current a bit. I have Lyen 12 fet controller run on 24s with no issues for quite some time. That is running at the edge of its limits though. I feel like I'm running near the limit with lyen 18fet. I wouldn't know where to run the Raptor on 24S though.
I finally got around to hooking up the E-brake cutoff and got to try out the CA cruise control. I still need to hook up another switch so I can enable regen with the ebrakes when cruising in the streets.
The CA V3 cruise control is really easy to use. Move the throttle and the cruise control disables. Hit the brakes and it disables. I have mine set at 6 seconds.
Added Magicshine super bright rear light on the rear shock reservoir. Spreaded the swing arm like 2 millimeters to stuff one of Zombies C-washer to give me more brake clearance. No more rubbing of the rotor against the caliper adapter.
Added a front fender to keep the junk out of my face when commuting to work and back.
