Portobello Commuter Bike
Up town style, down town tough
Getting the best out of big tyres has made our mountain bikes multi-award-winners and we’ve applied that same, bigger-is-better mantra to our awesome urban bikes. Sitting the Portobello on oversized WTB 650B balloon tyres gives it a smoother, grippier ride that can shrug off kerbs and potholes but still accelerate fast enough to put you in pole position in the traffic light Grand Prix.
We’re also not going to deny that the visual appeal of the big, tan wall tyres is another advantage - especially when teamed with our sleek, subtly curved, lightweight alloy MTB-influenced frame and fork. The same dirt DNA informs our choice of wide-range Shimano gears and powerful hydraulic disc brakes making this one seriously impressive road rocket that still packs all the features to be totally practical.
