FAQ

What tire should I run on my rear with a 21" front upgrade?

If you keep your OEM 19" rim, you should select a 100/90-19 tire from here to match your 21" front.  The 100/90-19 is the perfect size and weight for your Ultra Bee.  Although larger tires will fit we highly recommend you do not go bigger due to the dramatic increase in weight which affects power and range.  Don't forget a new tube for your larger rear tire, you cannot use your OEM tube it's too small.

 

Will Traction Control still work with a 21" front?

Warp9 is the only wheel that comes with new traction control rings for wheel size changes on the Ultra Bee.  If you want to retain traction control be sure to purchase Warp9.
