Yo! So it's been a while since I've posted or built something, but I'm back. After a lot of working from home, I'm back to commuting to SF, so that means I need a scooter to get from the parking lot to the train and from the train to work, plus ripping around SF on my lunch.
I still have the dual hub beast that's pretty fast (36mph), but not ideal for commuting. With this build I had 3 simple rules.
1. Must look stock
2. 25 mph top speed
3. Super light (carry with one hand)
With that in mind, I knew a razor was going to be a good candidate. I've built a few e300s back in the day but that's a little bigger than I want. Searching facebook marketplace I found a razor Rx200 off road edition for $45! I knew that was the one as soon as I saw it, so I grabbed it immediately. I had a few outunners, castle 50 esc, and a new 6s turnigy nanotec 8ah lipo sitting on my bench. These will work nicely for experimenting.
I made an adapter plate that mounts to the original motor mount holes so there is no need to modify the frame. I added long slots for the mount to provide perfect chain alignment. I made a quick mount for the actual motor out of some scrap aluminum and off we go. I got the motor mounted and wired up first. I had an old servo tester and magura throttle in my stash so I had the whole system up and running pretty quickly. I knew the 50A esc was on the small side but wanted to experiment with it. I ordered a 180 esc off of bangood which is wired up and feeding lots of current to the motor. I mounted a 10t sprocket on the front and used the same chain that came with the scooter, it was really a breeze getting this together.
Specs (so far)
19mph top speed
Wheelies on demand up to 12mph
about 8lbs lighter
I also ordered a new motor off of ebay which is a 170kv and an 11t sprocket. I plan to hook up my watt meter to see what the 245kv motor is pushing, then I'm going to swap the motor to the 170kv and see what the specs are with that motor. I will post all this data later. I'll also take some better pics and get video. I'm commuting on the scooter daily and have about 10 miles on it. I'm slowly working on it at night when I can find time. I hope to have all the parts and what not within a week, so maybe the build will wrap up within a month.
