GRAND RAPIDS, Mich. — For spring 2021, TerraTrike is going big with an ambitious new model inspired by its popular Gran Tourismo, and the result is a faster, more stable and more comfortable ride. The Gran Tourismo Sport, or GTS, is TerraTrike’s entry to the growing category of all-road endurance cycling – it’s quick enough to jump into a fast group ride, but comfortable enough for hours-long gran fondos.

Posted on April 9, 2021 by Larry Varney Jason Dubin has been hit by cars while riding his recumbent bikes and velomobiles in the streets of New York city many times. He joins us to share video and commentary of 3 of these horrifying collisions and talk about his personal safety. Then we widen the discussion with Steve Magas “Ohio’s Bike Lawyer” and our panel to put bent safety into some context and search out the best way for us all to avoid becoming another sad roadside statistic. Honza will present the news, Denny is back with his sports report, Nina Paley leads off our new Bent Product Review series with a look at the Mango velomobile and Doug returns with another “Bent Road Fixes” segment. Laidback Bike Report March 14! Posted on March 13, 2021 by Larry Varney It’ll be crazy fun hearing from the boys of the British Human Power Club on March 14th’s webcast.

"Having the Loopwheels has been a complete life changer for me. I can now go on longer journeys with less fatigue...."
.
For me, base on this design, as long as you can maintain the hub to be: ground to hub distance would always be greater than the hub to the horizontal distance (radius) to the rim. then you should be fine.
A vehicle’s suspension is a series of shock absorbing parts and springs that keep your car driving straight, and from bouncing too hard when riding over bumps. It also helps out with the braking process and keeps the body of your vehicle attached to the wheels.

Without a suspension system, the car’s wheels would hit a bump and move up and down perpendicular to the road surface. This vertical energy would be transferred to the car’s frame, which would pull the wheels away from the road before gravity takes over and slams the car down. The suspension system must be finely tuned using a combination of springs and shock absorbers to reduce these effects for a comfortable and smooth ride.
Loopwheel springs are made from a carbon composite material, carefully developed and tested to give optimum compression and lateral stability as well as strength and durability. Specially-designed connectors attach the springs to the hub and rim. The three loops in each wheel work together as a self-correcting system. This spring system between the hub and the rim of the wheel provides suspension that constantly adjusts to uneven terrain – cushioning the rider from bumps and potholes in the road. In effect, the hub floats within the rim, adjusting constantly as shocks from an uneven road hit the rim of the wheel. The spring configuration allows the torque to be transferred smoothly between the hub and the rim.
GRAND RAPIDS, Mich. — New for 2021, TerraTrike’s Rogue creates a whole new level of comfort and ease in cycling, a complete departure from the world of finicky, clunky shifting. The Rogue’s internally geared Enviolo hub offers an infinite range of seamless shifting – from a standstill or under load – without the noise of idler pulleys or the constant tuning of derailleurs.

In My case, I'm building a gantry with multiple axis of movement, as a means of making construction easier (the gantry would be used to, say, grab a WIP and lift, shift, and rotate it so I could get to otherwise inaccessible sections of the WIP).

Loopwheels launched their journey into production off the back of two highly successful Kickstarter campaigns in 2013 & 2015 where the response from the community was astounding. The brand has since expanded worldwide and now distributes products to over 20 countries.
“Why would you want to lower it?” an unnamed Audi product planner asked when I’d shared my plans for the e-tron with him. “It’ll look like an Avant.”
looks like the idea could be refined a bit in the direction of this Military version with an airless tire…flat proof and comfortable commuter tire would be sick. Daver on April 15th, 2013 - 5:45am Luiggi on April 15th, 2013 - 7:21am
