Frequently Asked Questions about Trike Conversion Kits.

Q: Can I install the Frankenstein Trike conversion kit myself ?
A: We have designed all of our kits to be so that can be installed by the owner. General mechanical knowledge is required.

Q: Is it a straight axle?
A: No, it is a "fixed axle" with a Dana 30 Differential (spider gears) which allows the inside wheel to turn slower while turning a corner.

Q: Does Frankenstein Trikes offer independent suspension?
A: No, during the design process we looked closely at the pros and cons of both systems. Additional weight and additional parts only increases the chances of something malfunctioning. Handling is also a factor, while cornering independent suspension will have a tendency to lean outward (just the opposite of what most people perceive). Independent suspension does have an advantage on a very rough road, although the disadvantages outweigh this advantage. If you think we're wrong, take a look under the body of the H-D Tri glide and you will find a "fixed axle rear end".

Q: How much does the Frankenstein Sport Trike add to the bike?
A: 120-150lbs. compared to 300-700lbs. with other manufactures' kits.

Q: What size tires and rims fit on the axle hub?
A: The hub accepts Ford bolt pattern 5 on 4 1/2" with 1/2"-20 threaded studs. The wheels' suggested size is 15x8 with 3 1/4" back spacing or 15x10 with 3 5/8" back spacing. If you choose to use your own wheels and/or tires our fenders and brackets may not work. Call for assistance when customizing your Trike.

Q: Do I need dual outboard brakes?
A: Frankenstein Trike Kits come standard with one caliper and rotor. This single brake provides plenty of stopping power. We offer outboard brakes if you anticipate towing a trailer with a considerable load.

Q: Do I have to install raked Triple Trees?
A: We highly recommend installing raked triple trees when converting to a trike. We offer the "POWER STEER' Triple Trees for all of our kits.

Q: Would I have to change my shocks?
A: No, all trike kit applications accept stock shocks. In cases where they do not, we include shocks with the Kit.

Q: Do I have to change any of my electrical components?
A: No, our kits are designed to not affect any of the electrical components.

Q: Would I have to change my exhaust system?
A: Stock exhaust will not work when converting a bike to a Frankenstein Trike. Short exhaust are typically used. We offer exhaust solutions for your conversion.

Q: Is the Trike stable while taking corners?
A: Since it is using a differential and car tires, the trike is very stable. But just like riding a two-wheeler, you can't take a sharp corner without using your best judgment.

Q: Can I convert my motorcycle with a shaft drive?
A: Not with our kit, sorry.
