brakes/hub motor question

Still enjoying my XB600 scoot...but wondering about something??? No problem...just curious how this works.

I realize that when you apply either the front brake or rear that power is cut to the motor...as with previous scooters I've owned. However, on my XB600 when I apply the front brake it is also doing something (electrically/electronically) in the motor that pretty much "brakes" the rear wheel as well. The back brake doesn't do this...only the front brake. What's the design behind this? I'd just like to understand how this works...and I'm guessing it's typical on all scooters with hub motors in the rear wheel, etc. Also, should I use the front brake less, more, equally...as the rear brake?

Also, so I don't have to go through the tutorial (downloads very slow) can somebody tell me how to post pics on here?) Thanks in advance for somebody's explanation on these items!

Re: brakes/hub motor question

It sounds like the front brake has a switch that switches on "regenerative braking". What this does is turn your hub motor into a generator - this causes it to act like a brake on the back wheel and sends current back into your battery pack.

However, I didn't think the XB600 had regen braking? :?

Re: brakes/hub motor question

Hmmmm....quite possibly. I know it holds the wheel pretty firm although you can still turn it with your hand using a good bit of force. Maybe ArticFox knows...but maybe not since he never sees the actual scooters as most all online dropshipping dealers. Also, maybe ArticFox knows what they mean on the add copy about "forward/reverse" capability. And while I'm mentioning ArticFox. Again, thanks to him for a great purchasing experience...top quality online dealer!

I sure hope x-treme gets better with their shipping...without damages, etc....and folks like ArticFox who offer number one customer service and high integrity can keep selling the x-treme scooters. In fact, knowing what I know about the shipping I'd pay the extra cost that they would incurr if x-treme would unbox and rebox these scooters much better so there wasn't the damages that are occurring. Course I think the shipping damages were mostly with the XM2000...but if you read my post about when I got my scooter there could have been damage the way mine came...obvious the whole scooter had leaned in box...yet I was just lucky and nothing was damaged.

I don't think the X-Treme XB-600 has regenerative braking, probably just band brakes front and rear.
Did you receive a Owners Manuel? There is a X-Treme User Manual Model:X-560 in our growing EV DownLoad Library that states:

Stopping/Braking
To brake, release the THROTTLE GRIP and depress the BRAKE LEVER on the left side of the handlebar. Depressing the brake will disengage power to the motor. When the unit feels like it is loosing power or not accelerating to full speed, the scooter is ready to be re-charged.
BRAKING SYSTEM
The X-560 uses a hub brake system on the front and rear wheel of the scooter activated by a hand brake lever on the left & right side of the handlebar. Make sure to release the HAND THROTTLE GRIP when engaging the brakes.
Practice braking on a smooth, dry surface to get used to the feel of the braking system. Braking distance is affected by wet conditions and loose and uneven riding surfaces.

BTW, if you have a Owners Manuel for the X-Treme XB-600, we'd love to have a copy to share with our members and guest.
If you have files to upload to our Library please send them to chas_stevenson [at] yahoo.com with subject File share and the name of the file.

Peace Out,

Re: brakes/hub motor question

Gman-

No band brakes here on the XB600. They are drum but with "shoes"...shoes that are fairly thick. Moving the lever moves a flat bar inside the drum which in turn pushes out on the top of each shoe as it rotates. And, in the case of the front brakes...it's not just cutting power to the motor. It actually does something that makes the rear tire w/hub motor very hard to turn. It's the best braking I've experienced on one of these scooters. I'd love to post some pics as well as the manual and if somebody can give me a quick instruction on doing that I'll be glad to scan the manual for posting. However, I just honestly don't have the time to download and read through the tutorial, etc....at least right now. Just email instructions to me.

Again though, this XB600 is well worth the money. If you're looking for highway speed then get the XM2000...but if you just want to zip around the neighborhood...through subdivisions, etc. you can all day at about 21-22 mph cruise. And like has been described about the XM2000 these scoots seem to just build momentum as you go down any slight incline in the road. Therefore, you can easily cruise along at 24+ mph if there's a slight slope going down.

Well, with those encouraging words, I guess I need to start a XB-600 thread like the XM-2000?

Even if the scooter does not have regenerative braking, it could still be turning the hub motor into a generator to get a braking effect and then just dumping the power into a resistor or something. I understand this is the way most locomotives worked until recently when somebody got the idea of saving that power.

I know nothing about this scooter in particular; just mentioning a possibility.
