For hill climbers
 

JUST FOR FUN...take a look at " GCN fun: Brompton hill climb" in the Folding Bikes section. The Brompton has a low gear in the mid 40's and a high gear in the mid 70's depending on the chainring which wasn't specified. The Brompton with 16" wheels is approximately 23 or 24 lbs. while the Orbea is the standard size high quality road bike weighing +/- 7 or 8 lbs. less. Andrew Feather is quite the engine.
