Thanks For the Links !! ... really interesting ! I like the single speed (am I alone on this ?
) On an idential commute I dont get any advantages on the 3 speed Brompton - Its lightly faster on down hill gradients where strida runs out of top speed (I'm not a spinner !). But strida is actually faster on the return uphill gradients (brompton gears are either just too low or just too high). But the rider makes more difference - a really fit guy on either bike would be faster !
For hilly rides I wouldn't take either of these (prefer a Whyte Mountain bike
)....... but for 90% of Rides to and across london Strida3 is my weapon of choice, throw in a few long corridors, or trips inside shops and Strida gets 100% - as it can be rolled on its wheels, and being long and thin doesn't get in anyone's way.
