'In 2007 I was sitting in an airport in Holland, and I noticed when a mother pushed a pushchair against a kerb, the baby was pushed forward. Morning, world! Breathtaking image of the first light of... A bright idea: The astonishing glow-in-the-dark GM plants...
They didn’t even mention the rim profile, surface treatment or wind tunnel results. I mean come on! Call me when there’s an aero version. Maxx on May 20th, 2016 - 11:05pm

Both modeling and experimental results demonstrate several realistic scenarios in which wheel hubs experience accelerations greater than 100g, sometimes at very low vehicle speeds. This paper focuses on the experimental determination of suitable design goals for in-hub motors (wheel motors), describing the experimental test rig, experiment procedures, and experimental results from testing conducted at UT-CEM. The paper also discusses implications of these results on wheel motor design, leading to the conclusion that a realizable and feasible design goal for a combat vehicle wheel motor shock rating is 150 g's, with a 10 to 20 ms pulse width.

We stock a range of other push rims, not all of which are listed here. If you’re not sure which to choose, please contact us as we’ll be happy to help.
The spring system between the hub and the rim of the wheel cushions the user from bumps and potholes in the road. The springs absorb road noise, reducing vibration through the frame and into the rider’s arms and body. High-pressure or puncture-resistant tyres can be used.
Instead of sharing a common axle, each wheel on a car with independent suspension is independently attached to the body or subframe. Different spring combinations may be used.
“Potholes, cracks, cobbles – when you have chronic pain, you feel every vibration like a knife. Loopwheels took only a second to fit. They definitely reduce the pain of going over bumps, kerbs and cobbles and have made every trip out far more comfortable.”
When taking on dunes, this off-road truck reduces shift times by 68%, sets its suspension on full damping and allows for moderate oversteer to impart maximum fun.
Also showing up for this jam packed webcast we have Honza with the recumbent news, Jason Dubin with his project to build and race velomobiles with New York City youth and then Ben Goodall owner of Trisled tells us about the newest update to the Rotovelo. With Recumbent Cycle-Con cancelled I’ve edited Chuck Coyne’s interview to reflect the history of the event, Mark Lovegrove from the UK talks about his two e-assist motor installations, Larry Varney reviews the AR3 tilting trike and Denny’s sports segment features John McWhae who just completed a record making ride across Alberta in spite of his battle with arthritis. 2021 Recumbent Cycle-Con Postponed Posted on July 31, 2021 by Larry Varney

That’s why you don’t want suspension between the ground and your hubs. Plus, many, many other reasons. potbellyjoe on May 20th, 2016 - 11:27pm

When you have plenty of bicycle to work with, such as is the case with a mountain bike, it’s not such a big deal to design it with front and rear suspension. When the bicycle in question is a diminutive folding city bike, however, it gets a bit trickier. That’s why UK industrial designer Sam Pearce has created Loopwheels. Instead of relying on a suspension fork and rear shock, it lets the bike’s 20-inch wheels absorb the bumps.

So, how did it turn out? Did I like the trike? What are the good points and bad? Before we get into that, I’m sure that there are many who want to see the specifications, and not have to read through to the end for that. So, here goes: Amazing New Bent Builds on Laidback Bike Report! Posted on June 5, 2021 by Larry Varney Today (Sunday, June 6th, at 2 PM EST), we literally get into the weeds with our Italian bent builder Marco Ruga. He has created an amazing off road long wheel base recumbent and will show us how he did it and where he rides it. Then Englishman Alex du Pre (who is a naval engineer) reveals his first recumbent design. A tilting trike/velomobile made initially out of wood. Doug is back with another gonzo bent road fix and we have two new Review Team segments: Joseph Janning from Germany talks about velomobile wheels and Mickey O;Brien from Laid Back Cycles in California reviews the ICE Adventure trike. Denny will cap it all off with the latest in sports and Honza has our recumbent news of the month. You can catch it all on YouTube Sunday, May 2nd at 2 pm ET or anytime thereafter right here: https://youtu.be/Zv7iotthpi0 Head over there now and click the “Set Reminder” Button! Live chat with our guests or panelist and be part of the fun. If you have questions/comments for our guests and can’t watch live please feel free to respond to this post and I’ll try to ask for you during the show.
