In a sight that's becoming quite common at the shop these days, some bluebirds tried out a Catrike 700. [In reality, only one bluebird tried the trike while the others watched.]

He liked the color and the lines, but found it too difficult to shift. Also, the headrest was too big.

We just got some Bionx 350W electric-assist systems in!

A little creative work, and we found a great spot to mount it on the HP Velotechnic Scorpion (tight spaces.)

AlphaBENT is now selling Bacchetta recumbent bikes!

With the shop fairly saturated with trikes, we have found that we haven't been adequately serving the two-wheel recumbent market.
