Xtreme XM-3150 Review
I too was recently bitten by the electric vehicle bug. I began spending most of my time reading about them on the Internet. I live four miles from work and the terrain (near Houston) is flat, and the fastest road I have to handle is a short stretch of 45 mph so a small electric scooter looked very feasible. The ZEV 400 LA would have been my first choice, but it was out of my $2000 budget.. Next I looked at the Zapino but it looked like they were trying to discontinue them so I began looking at the Extreme line up. The XM-3000 series had a bit of a rough reputation but the latest revision (the XM-3150) promised (of course) to be much improved. Even though I couldn’t find any recent reviews of this model, I bit the bullet and ordered it online from Advanced Electric Scooters (dot com), for $1999, which included free shipping to my door.
I ordered it on a Thursday evening and immediately received a confirmation e-mail along with another one the next day from Green Max also confirming the order. On Monday, UPS Freight called to set up a deliver date for Wednesday between 5 and 7 pm. While I was still at work, the truck driver called to ask if he could drop it off early (3:30 pm) and I took off work a little early to meet the bike.
The driver already had it in my driveway when I arrived and I was glad to see it was in good shape. After I cut away the carton I saw that the metal crate was the same cheesy quality as the one that brought my generic 150cc GY6 scooter in 2008, but this time they used lock nuts and strapped to a real live wooden pallet. The result both times was no damage. The manufacture date was 3/10/2010
I plugged the charger in while I figured out a way to get it out of the crate, which I eventually did by myself. Thank goodness the welds are cheap and most can be broken with a claw hammer. I got the feeling they were made by elementary school children learning to weld with Harbor Freight cracker boxes. Anyway….
My patience lasted until the 85% charge LED was lit before I ventured out for a test ride. My first impressions were very smooth, quiet, and powerful. The infamous 2 speed “power/economy” switch (which was not mentioned at all by the manual) was located under the seat nearby the circuit breaker and the charger port. It is a three position rocker switch labeled I, O, and II. I is low speed, II is high speed (I haven’t tried ‘O’)
After a full overnight charge, Day two observations are that, while it is still smooth, quiet, and powerful, it handles weird and takes some getting used to. Despite adjustable (for ride height) shocks, it still sits relatively high on the lowest setting and might benefit from some shorter shocks. Of course, that might make the steering even more heavy, who knows. Be sure and check your tire pressure - mine came with 58 psi in the front and 68 in the back. I dropped mine to 38 front, 40 rear.
The other issue is throttle sensitivity - Acceleration is so strong and the fly by wire twist grip is so light that it is hard to regulate over bumps. I’m starting to wonder if it has a problem. Also, my range is not looking too great. It seems to need an hour of charge for every five miles that you travel. My first trips were only 5,5,& 10 miles while I attempt to ‘condition’ the batteries. Along with a cable driven odometer / speedometer, it has an analog voltmeter with only green, yellow, and red areas to monitor charge. I’ll know more as I gain experience. The one area that doesn’t need improvement is performance. This thing is fast. It’ll blow my 38 mph 50cc Yamaha Vino in the weeds. Be careful who you let drive it. Power is strong and can be abrupt even on the low setting..
Fit and finish are generally great where you can see, but if you poke around underneath, not so much. It has a few nice un-advertised features like a turn signal beeper. Also included are some LEDs. The red one indicates that ‘power is on”. There are two more little blue ones. The left one comes on anytime the brake or kickstand is activated. The right on comes on if the motor is overheated. The left one is so laser bright that it will blind you at night when you put the brakes on. The charger looks like it has been upgraded. The way the manual reads, the builder is obviously proud of its advanced capabilities, however the translations still have a long way to go.
Overall, I’m very pleased. it’s a lot of electric scooter for $1999. I think I’ll put off that 72 volt mod and look for some shorter shocks. And of course we’ll have to find a way to enable that regen! Sparc5, do you know how?
