The two riders are positioned on the bicycle back to back. A differential unit is mounted on a recumbent tandem bicycle in order to allow 2 different inexperienced riders to enjoy and even race together...the whole unit was designed by students for their capstone project. There were two teams for this project where one team was in charge of structural frame design while another team was in charge of designing the drive-train system. The current prototype uses the differential unit as a power combining mechanism to transmit two inputs to one output and is mounted on pillow-box bearings and has two input sprockets that are fixed to the input shafts, as a result for this current configuration in order to apply the force the riders must keep their feet on the pedals at all times.. to alleviate this problem a possible solution is to use a backstopping freewheel instead of the pillow-box bearings while the two input sprockets are also changed to freewheels that only apply the force in one direction...also the current setup requires the rear driver to pedal backwards unless a reversing mechanism such as two gears are implemented as well for one possible solution. thank you for checking out the project........ :-)

A tricycle built for two? You bet!
The TerraTrike Tandem is a great solution for those looking to ride with a companion. The frame coupling system separates the trike into 2 pieces to allow for easy transport and optional independent pedaling system (IPS) lets one person pedal while the other coasts. With this setup, you don't need to have perfect coordination with your partner to have a smooth ride. And if you want to stop pedaling and make your partner do all the work, this is definitely the system for you.
Never has a leisurely bike ride with your companion been so much fun. Pedal in comfort and turn heads, all while getting great exercise. The Tandem is built solid to withstand long distance rides and handles smoothly to allow for a riding experience like no other. You will laugh yourself silly as you fly down the bike paths at incredible speeds.

The Rover is bringing triking to the masses! However, be assured this is NOT your grandmother's trike! With its higher seat, tighter turning radius, easy adjustability and simple assembly / dis-assembly to allow for easy transport, you may find the Rover to be the last trike you ever buy. And at this price, everyone in the family can afford one!
The main feature of the Rover is it's new seat. A full 4 inches higher than most other tadpole trikes on the market; it is the same height as a standard office chair. This makes getting in and out of it a breeze - even no-handed! This also puts the rider at almost eye level with most standard car drivers for better visibility and safety. The seat is also fitted with a special adjustment clamp allowing for quick adjustments from very short sizes to very large sizes - all with the quick flip of a lever. The frame is also easily adjustable giving you even more sizing options. Go from your young child to Shaq sized in just minutes. All with the same trike.
The Rover's ingenious design also provides for easy transportation. The trike is comprised of 4 elements that all bolt together within 5 minutes. This makes it very simple to break down and transport in a standard car. Now you can easily take your trike with you on vacations, camping and family trips.
Because of the design, it has a very small turning radius (In most cases even shorter than a standard upright bicycle). You can take your Rover into places that had never before been accessible to trikes. Another great factor of the design is the absence of any idler wheels. The simple chain routing along with the internally geared rear hub makes the trike extremely quiet, efficient and nearly maintenance free.
The Rover also ships with an assortment of 8 different colored decal packs. Customize your Rover to your preferred color or mix and match to produce a one-of-a-kind trike. - This Tandem version also converts into a single 8 speed version too.
