4: Up hill- this is where i think you may encounter difficulty. since its a climb. assume that you follow case 1, then you should be at least fine here. you have to focus on the ground distance to hub must always be greater than radius of wheel parallel to inclination of climb. (because imagine case 1, if your hub is no longer at the center, you will be lifting your self. in an inclined position. more difficult than lifting in a plane.

The steering and suspension systems are important for both your safety and comfort when driving as they ensure a smooth ride as your car travels over bumpy roads. The two systems are usually talked about together as they are directly related to each other. However, what does each system do? When do you need to check these important systems? And, how can you tell if either system is damaged in some way?
Also, look around for any other gear you might need for the coming season of riding.

With any wheels there is always a little trepidation about hitting larger more inanimate objects but with Sam goading me on I started to aim for rocks, ruts and tree roots (did I mention we were riding off road!!!) and in every instance the wheels soaked up the impact, leaving me free to ride the bike without worry of knackered rims, aching arms or even getting up out of the saddle to soak up the impact – you can just let the wheels do the work.
Power Wheels Suspension
Bicycle wheels often follow a standard convention. They contain metal rods known as spokes that radiate from a center hub. The spokes provide strength in all directions as the force of the rider bears down on the wheel. The design of spoke wheels hasn't changed much in the past, but Chet Baigh has a new approach.
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.

I played with the idea using steel springs in wagon wheels for a Ring of Fire series fanfic (I highly recommend the books if you like time travel stories) but I am not convinced that loopwheels are a better solution than a springy seat post.

Shock Absorbing Wheels
Things turn even further in the favor of the ASW system if you factor in punctures, blowouts, tire fires and how long a truck has to be out of service each year while those monster tires get changed. ASW treads are bolt-on, bolt-off chunks that can be changed with very little gear, without even jacking any wheels up, and done in sections during shift changes and lunch breaks so the truck's never out of service due to tires. They can also ship much more cheaply, since the whole assembly can be broken down into bits that easily fit in a regular shipping container.
So how does it work? Well, a suspension fork (spoke suspension) only works on one plane. The Loopwheels on the other hand, provide what Loopwheels call, “tangential suspension.” Basically, they work in every direction, according to Loopwheels.com. So, they respond “to a force hit head-on in the same way as they do to a force from above or below.” This gives riders a smooth ride, instead of the lumpy, vibrating ride they are used to.

According to Pearce, one of the advantages of Loopwheels is the fact that unlike a suspension fork, they can absorb shocks delivered not just from underneath or above but also from the front (as might happen when running into a curb head-on). He also admits that many other inventors have come up with designs for wheels with tangential suspension over the past hundred years or so, although he believes that today’s modern materials will allow his to work where others have proved impractical.

If the SoftWheel catches on in the way Barel thinks it will, Israel will become a world center of wheel technology and production. “Nearly all the materials we use to produce our wheels are made in Israel, and we are currently building a large production facility in northern Israel to build SoftWheels,” said Barel. “This, like our product, is an innovation as well, because not too many industrial products are made in Israel. All around we are developing a new paradigm, one we believe the world will embrace.”

Founder Sam Pearce describes his design idea: “In 2007 my idea of a wheel with tangential suspension was born when I was sitting at Eindhoven airport waiting for a flight. I saw a mother pushing her child in a buggy. The front wheels hit a slight kerb and the child jolted forward because of the impact. I asked myself why a wheel couldn’t have suspension inside it, so it would soften an impact from any direction. I sketched the idea in my notebook, got on my flight, and didn’t think much more about it for a couple of years.”

The airline industry is already in touch with SoftWheel, and the company sees immense potential there. But planes and automobiles will have to wait a while, Barel said, as the Israeli firm is focused first on wheelchairs and bikes.
'I suddenly wondered why the wheel couldn't have its own suspension, and quickly drew the idea down - and then did nothing about it for two years.
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.

Repairs aren't the only pricey setback, When it comes time to replace a high-performance, low-profile tire, the cost can be staggering. Take, for example, the 2011 Chrysler 300C AWD. By the time 35,000 miles pass, according to TireRack.com, you'll be looking at an $1,128 bill if you opt for the factory Michelin Pilot HX MXM4 tires in 235/55R19 size, not including mount, balance, tire disposal, or the four-wheel alignment that's always a good idea before investing in new rubber.

I’m beginning my return and hopefully the next one doesn’t have this issue. Is there something on the user end that can cause this or is this something that was just wrong with the manufacturing? I put this bike together per the instructions. I rode it down my driveway and hit the brakes. When I did so the front tire instantly moved to the side and started rubbing the forks. I thought maybe I did something wrong so I read over the instructions and made the front wheel a little tighter. Still got the same result. Definitely going to try to return this thing. Just sucks I spent all that time putting it together and now I have to deal with shipping it back.

A loopwheel doesn’t have the same rigidity and stiffness that’s necessary in a spoked wheel.
This tri-shock wheel concept could, conceivably, make singletrack and downhill even less jarring. But with every bump that’s softened, there’s a little more energy that’s drained from the ride itself.
The arm may be broadened into a V shape with two pivots, either side by side or with the inner pivot slightly behind the front one - a semi-trailing arm. Trailing arms are usually found at the rear only. A trailing-arm suspension on a rear-wheel-drive car. The arm is attached to the rear wheel hub and broadens into a V whose two arms extend forward to pivot on the frame. The differential is fixed to the frame and the drive shafts have universal joints.

Isn’t this criticism true of the vast majority of front suspension systems on the market though? Other than a few crazy linkage equipped forks that never really caught on, compression of a suspension fork will steepen the head angle and shorten the wheelbase too. dorkdisk on May 20th, 2016 - 2:25pm

Within 20 metres you notice how smooth the ride is, looking down and you see that its not fresh tarmac, rather it’s a country road, yet the ride gives no indication of the road surface, its just smooth – you are feeling the road rather than the grotty surface.

The design most likely requires a drum or disc brake since the rim’s position would likely change too much for rim brakes. We’re thinking this could be a fun design for commuter and city bikes where aerodynamics and weight are slightly trumped by comfort, particularly where the streets are a bit rough.

Please take the time to register and you will gain a lot of great new features including; the ability to participate in discussions, network with other RV owners, see fewer ads, upload photographs, create an RV blog, send private messages and so much, much more! Personally I don't like to lift wheels off the ground with the jacks and I would never lift the drives off the ground. If it's so unlevel that the wheels would be off the ground, I'll run up on some boards first to get close, then finish leveling with the jacks. Fronts are ok. You won’t damage anything. As stated above, never the rears (drive wheels) because the parking brakes are on the rears. If you’re not comfortable with the fronts being off the ground, you can build some small ramps or wood blocks you can drive the front wheels onto. If you search for ramps on this forum you’ll find lots of examples. When an air bag RV is lifted, ONLY the axle weight is left on the ground. no matter the lift height. This is unlike a leaf or coil spring vehicle. The tires provide limited stopping. If the leveler pads are on softer ground, they will put much restriction to the RV moving sideways as the pads will be in a hole. The suspension system has no problem handing from the shocks / limit straps. It endures FAR greater stress while you are driving down the road soaking up the bumps and road heaves. All that being said, try to NOT lift the RV any further up than is required. Things inevitably break. Hydraulic lines, solenoids, seals etc. You don't want a single leg to drop on it's own which the torques the chassis. An RV up in the air is invitation to crawl underneath or store stuff under. Not good when something breaks. So, pick a more level spot or use blocks to get the rig as level as you can before lifting. Don't park on a hill and lift so that there is no chance of slipping sideways (tire and / or leveling pad friction). Your drive axle (brakes) always have to be on the ground... else you'll go down hill as soon after you've walked bow to stern inside the coach a few times... I don't like to lift either off the ground ever. I only use the jacks enough to level the final little bit and to not have the coach shake while moving around in it. The thread Sonic posted is great! I use 2x10s like suggested in the posted link, but took it slightly further. I didn't cut an angle, don't really need it and in the past I found that it sometimes gives them the ability to slip while driving onto them. I would post pictures but it is in the shop for engine repair and the boards are in unit. Basically I took 2x10s and cut 2 boards the longest that would fit in the bay I was storing them in (about 36 inches long). I then cut 3 more boards about 8 inches shorter (for a total of 4 boards high), so lenghts of, 12, 20, 28, 36 long. I have 2 sets in case there is a need for the rear duals to go on boards. To keep the boards from sliding when driving onto them, I bought 3 different size carriage bolts that would go through 2, 3, or 4 boards but not all the way through, just long enough to keep them stable as you drive. I then took a spade bit that was 1/8 inch larger than the bolts and drilled through all 4 boards to accommodate the bolts, i did this in the rear where they would line up even and no worry about puncturing tires if they popped up slightly. I then took a spade bit slightly larger than the bolt head, and drilled on top of the holes the thickness of the bolt head. This way they sit down flush with the boards. It works very well! For the jack pads, I couldn't use anything very thick, as if I am on level ground and I dump the air, I only have about 4 inches between the jack pad and ground. I took 2x4s, and cut them the length of 3 2x4s put next to each other. I cut 6 in total. I then laid them crossways (think the first 2 layers of Jenga) and nailed them together from both sides. These work great for leveling! When i get it back from the shop next week I will try to remember to post some pictures. Your drive axle (brakes) always have to be on the ground... else you'll go down hill as soon after you've walked bow to stern inside the coach a few times...
