The Verge X20 is fast, very fast. Smooth, balanced and stops on a sixpence. I loved it. No flex, no judder, just confidence and the largest smile of the day.

"The Verge X10 is an awfully quick little rig, scooting forward with each pedal stroke and maintaining a healthy clip in an efficient-feeling manner that's more befitting of a mid-ranged road bike than something intended for commuting. Perhaps most telling is the fact that we often grabbed the Verge X10 if we were running late for something (which was pretty much always)."

"What surprised me the most, was the Kinetix pro wheelset and the stock-standard Schwalbe Durano tires. I’ve underestimated them, thinking that it was flimsy and unable to take my weight. With a Godzilla-sized rider like me, the rims and tires were able to withstand our harsh road conditions. Not only that, its capable of yielding 25km/h on the average with little effort. So, imagine if you are really fit and have the power to weight ratio. This bike will fly!"

"Setup couldn't be simpler: Flip a lever to unfasten the main body and fold the bike in half, flip a level on the handlebars to fold those down, push in the pedals, and lower the seat . . . the Verge Duo was a comfortable breeze to drive around bumpy, hill-heavy Brooklyn bike paths. Finally, at less than $1,000, it's a steal when compared with its pricier U.K.-built competitors."

"The Tern Verge X30h is by far the fastest folding bike I have ever ridden. At just under 23 lbs the X30h feels like you’re riding air. Normally, when I come to a stop light, I jump forward off of the seat and rest my foot on the right pedal in anticipation of the green light, but, with the X30h, even the weight of my foot was enough to make the bike creep forward, as though the bike wanted to speed off right out from under me."

"The combination of performance, speed, reliability, maintainability, and reasonable if not low pricing, will make this the right choice for many weekend road warriors who want or need a fast, folding, commuter."

"The components and technology are second-to-none. The gear range is wide enough to cover anything you’ll tackle in the urban environment: a SRAM 11-36T cassette, and an FSA 55T chainring. Changing gear is smooth, and the bike runs silently. The Double Truss frame is stiff and responsive to the power you put through it. The TIG welding is as beautiful as it is functional. Forget even the folding aspect, because it’s just a great bike."
