The Trike Shop ::: Thunder TS

Hit the road with the THUNDER TS Conversion kit and experience the trike-riding difference. With a longer wheelbase, generous additional storage, independent suspension, optional electric reverse and disc brakes, you may never want to return home!

Every THUNDER TS Conversion kit is built with the attention and craftsmanship needed to be a true extension of the bike itself. Take a closer look and you will see what we mean.

Reliable design
The dual lateral trailing arm style suspension gives the rider a smooth ride and the added benefit of very few moving parts. The trailing arms actually only have two moving parts. The two urethane bushings that attach the arms to the frame are designed for automotive use and in this application should last forever. This eliminates the possibility of something wearing and changing the wheels alignment. And we use “off the shelf” automotive wheel bearings for easy serviceability if needed.

Longer wheelbase
We increase the wheelbase of our trike conversion for two main reasons. One, because a longer wheel based vehicle always rides better than a shorter. The stock wheelbase puts the passenger right above the wheel, making them more likely to feel every bump. By moving the rear wheels back the passenger now sits ahead of the wheels thereby giving them a must better ride. The other benefit is that the passengers feet are not crowded by the rear fenders.

True track stabilizer bar
The stabilizer bar also known as a sway bar is a flexible link between the two trailing arms. The bar uses the torsion effect to always try to keep the trike righted or sitting square to the ground. The beauty of the stabilizer bar is the fact then when one wheel hits a bump the bar can flex quickly to absorb the movement then return. This is the same technology used in almost every car and truck today. Anyone that tells you Independent Suspension trikes lean outward in a corner is right. But that’s no different than any other car, SUV, or ATV. A little body roll, and it is just a little, is a good thing. Just think if you had “no lean” that means your trike is always perfectly square to the ground. In affect, if you go over a 2” bump with your right wheel the trike rocks up 2”. But with Independent Suspension, just that wheel goes up. The antiquated solid axle system is only made today because it’s cheaper and easier. Technology has improved a lot in the short history of trike conversions, but some are too stuck in their ways. We offer only the most innovative designs to our customers.

Adjustable coil springs
The coil over nitrogen charged shocks are the key to the Ultras smooth ride. These are the type of shocks used in everything from race cars to street rods. They have adjustable compression dampening and spring preload.

Disc brakes
All of our belt conversion kits feature an extra large 9” disc brake system. These automotive brakes have more stopping power than you can believe. That’s one of the great features of a trike is how easily the stop, no matter the road conditions. We also use “off the shelf” parts for all of the brake system, but you’ll probably never wear a set out.

Trailer hitch
You’ll find that hauling a trailer behind a trike is nothing like it was as a bike. With the increased foot print, added weight and massive brakes you’ll truly forget its back there. Our receiver style hitch solidly bolts to our frame way up on our frame near the bike.

Multi point attachment
With the understanding that a trike puts different forces onto a bike frame than it was designed for, we believe that frame attachment is critical to a long lasting dependable trike conversion. Our kit bolts on at multiple points thereby reducing the force at any single given point. The frame includes a large steel tube attached, down low, near where the swing arm attached to the frame. This gives the bikes frame a lot of added strength. The fact that the tube ties together the frame rails makes them much stronger as a whole. The trailing arms are attached to this solidly mounted tube.

Heavy duty differential.
We use an automotive style differential reconfigured to be part of an independent suspension system. We use a standard ring and pinion configuration installed in a cylinder shaped housing. That unit is mounted within two large auto centering bearings. That whole assembly rotates with the sprocket mounted to the one end. The differential is packed solid with moly grease that never needs servicing. A benefit of this design is that the gears only move a when you turn the trike. The other end of our differential mounts our innovative parking brake. All of this and again using “off the shelf” components for the best serviceability.

Belt
We change the belt with our conversion because of the longer wheelbase. The belt we use is a Gates Polychain GT2. This is the best possible belt to use on a motorcycle. They are extremely resistant to stretching or wearing.

Durable CV joints
The axles are custom made for our conversion kits, but the constant velocity (CV) joints are standard automotive applications. We use automotive type parts for all of our drive train because it’s designed for a much heavier load, meaning these parts will probably last forever in this light duty application. Again using off the shelf parts for your convenience
Easy bolt on installation
Our kits are designed to install easily. We pre-assemble so much of the suspension system before it leaves the factory, installation time for the technician is minimal. Not that is should be a race to just through it together. We just feel ease of installation means there are less possibilities of mistakes or mis-adjustments. With our kits there is no special aligning or measuring required. This also allows us to sell our kits directly to the bike owner and let them install the kit themselves.

Have Fun, Worry-Free
We offer the best warranty in the industry. Your trike comes with a full 3 year 1,000,000 mile warranty on the entire trike kit. With our experience producing this type of conversion kit, we can offer this warranty because we just don't have problems
