Allen Sports Ultra X Superlight Carbon Folding Bike Review

The Allen Sports Ultra X Superlight is appropriately named. It weighs in at 18.75 pounds and on top of being “super light” it looks pretty cool too.

This bike is constructed with carbon fiber.  Every part that could be carbon is: frame, forks, crankset, rims, seat post, seat, handlebar post, and handlebars. Carbon fiber is what allows the Ultra X to be light but strong at the same time. It’s also the reason this bike looks like a bike and not a spaceship. The Ultra X is more than 5 lbs lighter than the Allen Sports XWay reviewed in one of our previous posts and we thought that bike was light.

All of the pros that we liked about the XWay are all there in the Ultra X. The same 451mm wheels and the same Sram X9 10-speed rear derailleur and Shimano 2-speed front derailleur. 20 speeds provides me with more than enough capability on my commute. This is a smooth ride and can really handle the hills. The Ultra X is the top of the line when it comes to folding bikes. Some might say it goes beyond what a folding bike should be.

This bike along with the rest of the Allen Sports folding bikes folds up nice and neat in seconds, but also becomes cart-like. I can fold it down and still roll it wherever I need to go. This feature isn’t something everyone is looking for, but I really enjoyed the design. Not all folding bikes are as easy to maneuver in their collapsed position.

Another thing I think worth noting is there isn’t a kickstand. I know with a bike like this I won’t ever want it out of reach, but that doesn’t mean I don’t need it to stand on its own every once in a while. Maybe adding a kickstand would have put this bike over the 19 pound mark, I don’t know. But for the price I’d like a kickstand and while we are at it a bell and a basket!

You can definitely get where you need to go on a less expensive, less flashy bike. There is no lying about that. Seriously, be committed to your commute and cycling lifestyle before considering the Allen Sports Ultra X. Check out Allen Sports to get more info.



  • Great design
  • Lightweight carbon
  • Amazing performance


  • Expensive
  • No kickstand

The Allen Sports Ultra X folding bicycle has the highest MSRP of $4,999. The price is a little bit outrageous. But this bike is a little bit outrageous and I haven’t come across another one like it.
