Cargo Bike Photos

Nice weather this afternoon, so I took the Frankenbike to the shops to pick up dog food supplies. Seeing as the light was so good I also took some photos of the bike – named after another Dead Poet, she’s Mary Shelley – for obvious reasons:

Mary Shelley, Frankenbike. Around 3m long and with a 7m turning circle.

From the front

Steering linkage & box detail

Steering linkage & prop stand. Yes – that’s made out of the front donor bike’s handlebars

A little titanium bling on the rear mech. Saving weight is important on this sort of bike!

… and ready to come home. Just 17kg on this trip, though I’ve had 50kg in there before. The weight makes the steering surprisingly positive – you point the bike and it goes in that direction.

  1. With 50Kg in the front it is just as well you saved 37g on the rear… 😉

    Exactly. Every little helps.

  3. A ver professional looking rig. How do V-brakes and ultra thin shimano chains hold up to the weight?

    You are right about the weight and steering. It’s the same on my Bakfiet, although I sometinmes feel like I’m driving a barge, so wide is the turning circle…

    The V-brakes are just fine, and the chain’s not a super-skinny one, so that’s OK too.

    The handling is at times a little “interesting” – I think it has three stable positions: straight ahead, or full lock either way. I think this is because the castor angle (the difference between the tyre’s contact point on the road and the line through the steering tube) isn’t large enough. I guess the BMX forks I’ve used are designed to be super-twitchy. Fortunately I think it’ll be fairly easy to modify them with a couple of bolted-on plates to move the front wheel ~1-2″ further forward. In the spring, maybe!

    Have you tried doing wheelies yet?
