This bike just wants to go fast

By Marc Cranch from CA, Ontario

I was actually looking at another Argon 18 and decided to take this for a spin just to see what it was like since it was out of my price range. There was an immediate response to the pedals when I started off, and the power generation was sooooo easy. Get one, you will love it!! Just looking for an E-119 now to add to the collection.

Ce vélo est très bien
