Ok, Tern has the Link D8 with 8 speeds giving 32"-85" range, 34x85x65 cm folded and 12.4kg.
Dahon has the Mariner D7 with 7 speeds 34"-92" range, 29x89x66 folded and 11.8kg.
Both bikes have fenders and a rack. There is a $1 difference in price. Both have a five year warranty. So the question is if those were your two choices which would you choose and why?
