E-Board Tracker Bike : A Small, Funny, and Eco Friendly Motorbike

TheFuture — Wed, 30 Sep 2009 08:43:30 +0000

The Eboard Tracker concept doesn’t focus on just a transport vehicle, rather the designer has envisioned it as an eco-friendly, small and funny motorbike that can run at up to 30 mph and ensures better twisting around the corner of the street with its compact and light design. This bike contains hand throttle instead of traditional electric pedaling and features light, simple and optical flowing frame. A beam girder from section-I and hydro-formed tubes welded together in order to strengthen the steering head. The handlebar is shaped like an ace-bar which is fully adjustable and includes a cycle computer on top with speed, battery status and estimated remaining battery capacity readings.

This bike features a very close to “vintage racer” look with its regenerative breaking and a hub battery since they are similar to a set of drum brakes. The chain is swapped for a carbon shaft, bevel drive and nylon hypoid gears enclosed in right swing arm. Behind the pedal shafts, a small six speed cassette type remains hidden and comes operational if the battery becomes flat any time. Both pedals are lockable at 180 degrees and can be used as foot pegs

Elliptigo Glide Bike

TheFuture — Mon, 11 Aug 2008 06:07:45 +0000

The “Elliptigo” is the new concept in bicycle designs that combines best aspects of running and cycling in the process creating a fun and effective outdoor exercise device. The overall device is quite innovative and different from the conventional bicycles that we have been used to. The user is in standing position and the pedaling motion is elliptical which is like running without impacting the body. It strengthens bones and muscles and is comfortable and safer compared to sitting and riding the bicycle. Unlike other bike designs, this bike is actually closer to reality. The device has eight different gears which enable a top speed of 25 miles an hour. So if you are in a mood to explore, go cycling!

Pi Electric Bicycle with Semi-Automatic 8-Speed Transmission

TheFuture — Thu, 03 Jul 2008 07:00:32 +0000

The Pi electric bicycle uses a semi-automatic 8-speed transmission to downshift into a lower gear for climbing hills, then up shift for rapid acceleration to a maximum of 20 mph on flats and allows you to pedal normally because the motor automatically disengages when not in use. Powered by a 750-watt electric motor housed in the horizontal chain and motor assembly, the Pi electric bicycle is capable of three modes of operation: electric motor power, human power, or the human-electric hybrid power combination. The electric motor and rider utilize the same 8 speed semi-automatic transmission making rapid acceleration from a stop or lower gears available for steep inclines possible (but with slower acceleration.

The motor automatically disengages from the pedals when desired so as to preserve battery life. Construction begins with a 12’ foot straight piece of 3⁄8-gauge, aircraft aluminum 6061 alloy that is roll-formed and annealed for uniform wall thickness into a complete 6′ diameter circular tube with a 4″ exterior diameter (the NiMH batteries reside within the tube from the front fork to the seat), which is then bisected to make a 6′ long arc for the bicycle’s frame. The sturdy frame supports riders up to 300 lbs.

The top of the arc provides a 26″ stand over height, allowing you to place both feet on the ground. The padded ergonomic gel seat provides for comfortable, relaxed riding. It attaches to the frame via a gas strut assembly that raises and lowers like a pneumatic office chair, accommodating riders between 5-7′ tall in a semi-recumbent position for ideal pedaling or powered coasting. A dynamo in the front wheel’s hub provides power for auxiliary lighting.

The bicycle has a range of up to 30 miles at 20 mph before requiring a five-hour re-charge from its AC adapter. Precisely tuned hydraulic disc brakes provide sure stops, and the wheels are made of dual-walled aluminum alloy and stainless-steel spokes; the 26″ semi-slick tires are ideal for roads or paved trails and use Presta valves. The bicycle is wet-painted in Rossa Corsa red using the same PPG color specification as high performance sports cars and treated with a clear coat finish for a luster that will last.

Modern Urban Folding Bike

TheFuture — Thu, 04 Oct 2007 13:00:03 +0000

Genius is a modern urban folding bike, ideal for commuters who need to travel short distances of 10 to 20 minutes between underground stations, the workplace and the home. It still rolls when folded and can therefore be comfortably used even in large congested cities. The compact design of the Genius ensures unlimited mobility. It can be carried, rolled or ridden, and with its well-thought-out functional and ergonomic design and release mechanism it is easy to handle. The aerodynamic look of the Genius makes it clear that this is not a child?s bike. Its three gears provide the necessary speed, and the bike can be unfolded and refolded within three seconds thanks to a convenient kick-bar and push-down / pull-up handle system. Made of aluminium (80 per cent) and stainless steel (10 per cent) it is lightweight, stable and 90 per cent recyclable.

Futuristic Dodge Tomahawk Motorcycle Concept

TheFuture — Thu, 09 Aug 2007 14:44:09 +0000

The Tomahawk is a Viper V-10 based motorcycle, a 500 horsepower engine with four wheels beneath it. The engine breathes through twin throttle bodies mounted right up front. The Tomahawk concept is an awesome-sounding machine. Clouds of blue smoke vied for attention with the throaty rumble of the mighty V-10, and hitting the gas visibly opened the twin throttle body blades up front where the headlight would normally be. Though deeper and more rumbling than most motorcycles, it did not seem to be louder overall – just deeper and less shrill.

The Dodge Tomahawk can reach 60 miles an hour in about 2.5 seconds, and has a theoretical top speed of nearly 400 mph. Each pair of wheels is separated by a few inches and each wheel has an independent suspension. Bernhard said four wheels were necessary to handle the power from the engine.
