Concept bike and HPV by Dennis Redmonds

This time trial bike concept rendering by German designer Dennis Redmonds caught my eye on the Velo Design blog Facebook page recently. Before you ask about the drivetrain details, or point out that the seat height is not adjustable, keep in mind that this is very likely purely a styling exercise. Definitely a nice form though… that could be developed into a working bike if it were to move past the concept stage.

See Redmonds’ idea for an tilt trike HPV below, and visit his Coroflot page for several additional renderings.

Curved cranks! Yay for designers.

The tilter looks nice. I wonder why this doesn’t already exist. Probably has to do with velomobiles already weighing a lot, and adding parts strong enough to hold a tilting frame and the mechanics behind it would have to add 10 more pounds.

Google on VeloTilt for a Dutch tilting velomobile in a further stage of development, there is a blog on the ongoing development of that project.

  Thanks Chief, I had forgotten about that one, but it was mentioned here a couple years ago. Need to post an update on that project. Drymer is another Dutch tilt trike that has been quite popular on this site. Another one that I would love to take for a test ride.

Re. ABG
Tilt trike concepts have been done a few times, are fairly simple and do not need to add a significant amount of weight. Think of the design as a chopper tricycle with an extreme long fork. Why this design has not really caught on is turning radius and stability. The bike would need to tilt over very far to do a sharp term, which can cause problems with geometry. And, because nearly all of the mass is on the “fork” of this super chopper tricycle, dynamic stability can be challenging. Not impossible, just difficult.
