Tern Link C7 Folding Bike
If finding a top quality folding bike and staying within a budget is your goal, the Tern Link C7 is the option you want to consider. Retailing at around $500, it was built with the budget-conscious shopper in mind. Although it is at the higher end of the budget pricing, it is worth it.
With Tern's patented DoubleTruss technology, this bike has a much stiffer frame and better power transfer from the pedals to the rear wheel. Unlike some of the other folding bikes, the Link C7 comes with 20-inch wheels (versus 16) and with 7 speeds. It's great for commuting and urban riding.
Weighing in at 27.5 pounds, and folding to approximately 13 x 33 x 25, it is a great size for a folding bike with 20-inch wheels. It comes with a flat handlebar, BioLogic Ergo grips, and cassette, shifter, and rear derailluer by Shimano.
The simple locking mechanisms on this folding bike make it an easy 10 seconds until you are unfolded and off for a fun day of riding.
