The Stringbike

Here at Velo Logic, we love creative thinking that the shatters preconceived notions of how a traditional component works or looks.

Today, here’s a quick look at a fresh new conception of the drivetrain.

We’ve seen chains, we’ve seen belts, we’ve seen direct drive, but we’ve never seen a string drive.

Stringbike - the carbon time trial versionWhat are the Advantages of the Stringbike?

Well here’s what they say on the Stringbike site, and I quote:

  • Silky smooth and almost silent riding experience
  • Less maintenance, fewer parts to malfunction, long-lasting high efficiency
  • No loose, broken, lost or rattling chains
  • No lubrication, oil, rust or dirty hands – clean bike, clean hands, clean clothes, clean environment
  • No chance of derailleurs going wrong and needing servicing
  • No costly chain and drive-system maintenance
  • Fewer bike parts exposed to possible damage while riding
  • Noticeably easier to climb uphill than with conventional bikes thanks to special riding characteristics of the drive
  • Almost continuous shifting through 19 gears, easily controlled by a single handle grip
  • Quick and easy removal of the rear wheel makes fixing flat tyres clean and hassle-free
  • The strings can be changed easily, without any tools in few minutes.

A basic StringbikeNo doubt it’s clever, unusual, creative, and it has some advantages… but I’d like to see a side-by-side comparison in terms of speed and efficiency, something like the results of riding traditional vs stringbike in a few 10-40 km time trials.

Nevertheless, interesting concept! What do you think?

Denny Utility Bicycle – Ready to Go

There’s a lot of new concept bike ideas in the works, I have mentioned a few, just last week I wrote about the DuBike.

Well there’s a pretty cool one that is going to be available soon, this year in fact. It’s the Denny Utility Bicycle and will be produced by Fuji bikes.

denny-utility-bicycle-1The basic idea behind the Denny is convenience. This bike is a workhorse, ready to go when you are, no fussing about.


Here’s some of the highlights:

• The handlebar does double duty as a lock
• Automatic gear shifting
• Electric power assist
• Fully-integrated, turn signals, head and brake lights
• Auto-on lights that react to natural light conditions
• Safety lights that flood light onto the road around the bike

Here’s a video of the Denny in action
