Cruising with ElliptiGO inventor Bryan at sunset along the Embarcadero

I met Bryan at Maker Faire, and immediately got the idea to get some DLG under the foot platforms of his invention on a sunset cruise. It was the first time we’ve mounted the DLG in a way that it moves relative to the frame of the bicycle.

Bryan invented the ElliptiGO out of frustration with driving to the gym to use the Elliptical trainers.

The last tandem I’d ever think to build

In the back to back tandem, riders face away from each other for an aero position. It’s pretty much the opposite of social biking

Tandem tall bike as seen during Critical Mass, Sept 2006

I’ve been thinking about building a Tandem Tall Bike. I like the up-down potential. This tandem shot at Critical Mass in Chicago, is an absolute stunner, and hints at the potential impact of a top-bottom tandem.

How to build a chopper bicycle without electricity

How to build a chopper bicycle without electricity

Chopper bicycle

With its bulging top tube and kinked handlebars, Monroe’s new ride shouts ‘Stretch Chopper.’ Even the large front wheel, while certainly outside of the standard chopper aesthetic, seems pleasantly contrary.

But while this frame was certainly chopped and dropped, it wasn’t welded. Monroe simply chopped an old JC Higgins cruiser frame and mated it to an Adams Trail-A-Bike (the kind used to help kids get the feeling of pedaling) and then pounded loops of chain down over the joints, where the two frames meet.

joints without welding

I had a chance to test-ride the chopper at the pier where Monroe works as a bike mechanic and metal worker. It was pretty satisfying. The leg extension wasn’t as full as I would have liked, but cruising and turning felt great.

Dave’s new Bionx installation. Looks like it was made for it, huh?

Dave’s new Bionx installation. Looks like it was made for it, huh?

Dave gave me a chance to test the Bionx on his Jai Bike prototype. It has four assist settings. Even on the lowest one, “1”, I felt a very solid boost.

“4” just made me laugh. It was so different from regular bicycling, I didn’t know what to make of it. But Dave’s analysis (and Todd’s from Clever Cycles) is that the electric assist is more for carrying heavy loads up hills than ‘cheating’ on the flats.

The problem is that once you have the 18 pound Bionx system installed on your rig, it will feel, well, 18 pounds slower unless you use the boost. So you’ll probably end up boosting all the time. The battery is easy to remove, but not the hub motor, obviously.

I’ve now ridden the Bionx, the Stokemonkey, and my friend Sean’s home brewed electric rig. I’ve enjoyed each test ride, but they don’t stick with me. I don’t wake up, ever, saying to myself “I need one of those.” I’m glad it’s out there as a car-trip-replacer, though.
