LocationRichmond, California United States map
Vehicle2007 Xtreme X-1200 custom
I took a cheap Xtreme X500 (basically a BladeZ copy)and have modified it into a fairly fast street scooter
MotorUnite Motor 1200 watt 48 volt 32 amp 3200 RPM Compound Wound DC
powerful motor. I believe they were designed for heavier Vespa looking electric gopeds
Drivetrain1200 Watt 48 Volt 32 amp United motor from TNC with a matching 50 amp controller
Controller Got this from TNC, rated at 48 volt 1500 watts 50a
wasn't too hard to wire this up. Only a few wires were different from the stock controller
Batteries4 Power Sonic high rate batteries 12 volt 10.5 AH, 12.00 Volt, Lead-Acid, Gel
These high rate batteries work great in scooters and electric bikes. They have very conservative ratings on the label for AH. Actual AH can be nearly double. They are heavier than the standard battery. Can put out much higher amps for short periods of time than regular batteries
System Voltage48 Volts
Charger
fan cooled 48 volt charger that came with scooter. Works OK for now, but only 1.5 amp
InstrumentationFound a really nice speedometer on eBay made for jogging strollers that works with tire size down to 5 inches. Also gives odometer readings, maximum speed, average speed, and RPM of tires. I hit over 1000 RPM tire speed going down a small hill at 33 MPH! That is freeway speed tire RPM's for a car. I static balanced my wheels with stick on car weights to make things spin better at these high RPM's.
Top Speed25 MPH (40 KPH)
I run a 13 tooth front and 54 rear. Nearly 10 MPH faster than stock, and it climbs any hill without hardly slowing down. I weigh 165 pounds
Acceleration3 or 4 seconds to 20 MPH
Range9 Miles (14 Kilometers)
I doubled the battery capacity by going to a larger and high rated battery. I had to make a shim so the deck would still close.
EV Miles
Current:80 Miles (128 Kilometers)
Seating Capacity1 adult
Curb Weight86 Pounds (39 Kilograms)
the batteries are 10 pounds heavier than stock + I added front suspension. It is up to a portly 88 pounds. What gets me is that all these scooters are advertised at weights without the batteries. Stock, this thing weighed 75 pounds, and it is listed at 60 in the literature. My friends RAD2Go weight 104 pounds and they say 85 in the ads
Tirescheap OE tires that wear quickly. I found some Kendas that I am going to get for the rear. On the front, I am running a larger 4 inch wide 11 inch high tire from a gas power scooter
Conversion Timeprobably 20 hours plus another 10 hours fixing all the junk parts that came on the scooter. hardest part was fitting the larger motor. I had to cut and weld an extension on the left side motor mount. Even the kickstand needed a re-design. They had 16 gauge wires running through a flimsy fuse holder that had to pass full battery current!
Conversion CostMotor and controller were on sale at $140. New seat and seat post shock (had to modify stock post holder)another $80.00. Front end redo with shocks cost about $100, so about $400 total including all misc. bits
Additional FeaturesI put no slip tape on the deck.

I am in the process right now of converting the solid front forks to twin front shocks with some stock parts from other scooters made by Bladez and Xtreme. UPDATE I spent all day and got the front suspension on and working. Used the larger tire from a Xtreme gas powered scooter as well. Upgraded the cheaply made head set bearings to Bladez ones while I was at it.

I do not recommend riding any scooter that goes over 20 MPH without some sort of front suspension. You can get out of whack in a hurry if you hit a pot hole on 10 inch tires at 25 MPH or faster.

It is a good idea to static balance the wheel on the high speed modified scooters. Get some stick on weights from a tire shop. Jack up the scooter and remove the brake pads, and with tire spinning freely, see where the heavy spot is by watching what spot always goes to the bottom when you give the wheel a slight spin. Put small weights on the opposite side in increasing amounts until the wheel will not go to a heavy bottom spot any more when given a slight push. You'll be smoother at high speeds and won't wear our bearings as fast.
sold the scooter last year
