James Huang, N-1 Bikes

It’s the best gravel bike l’ve ever ridden, and one of the best bikes I’ve ever ridden.

...a fresh take on what a gravel bike can be... a balance between shredding single-track and winning races.

Betsy Welch
VeloNews

It’s an exceptional bicycle... a well-crafted piece of machinery that I would go so far to describe as a form of art.

Rachel Jary
Rouleur

From the moment you swing a leg over the saddle, there’s no denying that this is a race bike. It’s feathery light, snaps like a whip and begs to go fast.

Anne-Marije Rook
Cycling Weekly

Possibly the zenith of custom carbon frame building, beautifully balanced with sublime ride quality and exceptional handling.

James Spender
Cyclist Magazine

...with a ride quality that sets a benchmark mainstream brands would do well to target. It’s that good.

James Huang
Cycling Tips

... This RM3 may very well be the finest-riding carbon bike l’ve ever had the pleasure to toss a leg over. This thing most definitely tugs at my heartstrings.
