The stock Ultra Bee wheels run out of ability exactly where real terrain begins. A 21" front and 18" rear is the enduro and motocross standard for a reason you feel within the first hour: the big front wheel rolls over rocks and roots instead of stopping against them, and the bike gains the ground clearance and approach angles the factory geometry never had.
This set is finished. 21×1.60 and 18×2.15 rims on 96 Power Parts hubs, silver spokes and nipples, Mitas Terra Force MX-MH Medium Hard tyres already fitted, Accel rimlock in place. No hunting for tyres, no booking a fitter, no waiting for a wheel build – you pull the stock wheels out and put these in.
Which 18/21 set for the Ultra Bee?
| Version | What you get | When to choose it |
|---|---|---|
| This set – ready built | Wheels + Mitas tyres fitted + rimlock. Black rims. Ships immediately. | You want to ride this weekend |
| Custom 18/21 | Wheels in any colour, no tyres. 2–3 week build time. | Colour matters and you pick your own tyres |
| Custom Excel 18/21 | Japanese Excel (Takasago) rims, no tyres. 2–3 week build time. | Top shelf, you race |
The price gap between this set and the custom one is the Mitas tyres, the rimlock, fitting and balancing, and immediate availability. If you have time and your own tyres, the custom version works out cheaper – link below.

Before you order
- Pick the sprocket option in the configurator above – no sprocket, 50T or 56T.
- You transfer the brake disc from your own wheel. Have the tools ready before you unbox.
- A 21/18 set raises the bike – worth considering if you are on the shorter side.
- Want a different rim colour? That is the custom version with a 2–3 week build, not this set.
Frequently asked
Does it fit without modification?
Yes, the set is plug'n'play for the Sur-Ron Ultra Bee. Move the disc and sprocket across from the stock wheels and ride.
Why is it more expensive than the custom set?
Because it includes Mitas Terra Force tyres, a rimlock, fitting and balancing – and above all it is in stock. The custom set comes without tyres and takes 2–3 weeks to build.
Can I get different tyres?
This set is built around Mitas Terra Force MX-MH Medium Hard. For a different model or compound we build a custom set instead – message us and we will spec it.
Can I buy just the front wheel?
Yes. The 21" front wheel is sold separately – link in the section below.
Alternatives and add-ons
Not sure 21/18 is your size?
Message us – we will advise based on where and how you ride. The set is in stock and ships from Poland immediately.
