The main purpose is for facilitating transport to disable peoples and also for movements of old people .The other main purpose is public transportation. Electric mover vary, with each offering a distinct combination of speed, compactness, ride, weight, durability, and price. Distinguished by the complexities of their , more demanding structural requirements, greater number of parts, and more specialized market appeal, electric mover may be more expensive than comparable non-electric mover. The choice of model, apart from cost considerations, is a matter of resolving the various practical requirements: a quick response, easy driving, or a faster but less compact model . Fig 1.1 : Electric mover for disable people Fig 1.2 :Electric scooter HISTORY 1.1 ELECTRIC WHEEL CHAIR The first records of wheeled seats being used for transporting disabled people date to three centuries later in China; the Chinese used early wheelbarrows to move people as well as heavy objects. A distinction between the two functions was not made for another several hundred years, around 525 AD, when images of wheeled chairs made specifically to carry people begin to occur in Chinese art. An electrically propelled tricycle was developed by the R.A. Harding company in England in the 1930s. The electric-powered wheelchair was invented by George Klein who worked for the National Research Council of Canada, to assist injured veterans after World War II. Wheelchair is used by people who have difficulty mobility. Motorized wheelchairs are useful for those unable to propel a manual wheelchair or who may need to use a wheelchair for distances or over terrain which would be fatiguing in a manual wheelchair. They may also be used not just by people with 'traditional' mobility impairments, but also by people with cardiovascular and fatigue-based conditions . Generally people who use are, -Disabled people -Patients at the hospital -Elderly people 1.2 ELECTRIC SCOOTER HISTORY Military interest in bicycles arose in the 1890s, and the French army and others deployed scooter for bicycle infantry use. In 1900, Mikael Pedersen developed for the British army a f version of his Pedersen bicycle that weighed 15 pounds and had 24 inch wheels. It included a rifle rack and was used in the Second Boer War. In 1941, during the Second World War, the British War Office called for a machine that weighed less than 23 lb (this was not achieved - the final weight was about 32 pounds) and would withstand being dropped by parachute. In response, the Birmingham Small Arms Company (BSA) developed a bicycle small enough to be taken in small gliders or on parachute jumps from aircraft. This British WWII Airborne BSA folding bicycle was rigged so that, when parachuted, the handlebars and seat were the first parts to hit the ground (as bent wheels would disable the scooter). BSA abandoned the traditional diamond bicycle design as too weak for the shock and instead made an elliptical frame of twin parallel tubes, one forming the top tube and seat stays, and the other the chainstay and down tube. The hinges were in front of the bottom bracket and in the corresponding position in front of the saddle, fastened by wing nuts. The peg pedals could be pushed in to avoid snagging and further reduce the space occupied during transit.

    DG504 | The Dutch way of biking Chester Maessen Yannick Brouwer Sway Leung Lisa Vork 1 Table of Contents Introduction • Market ● End user insight ● Channel ● Competition • Value Proposition ● Concept ● Benefits ● Moneyflow • Technology ● Functions & Modules ● Needed Capabilities • Dynamics ● Market ● Technology ● Risk assessment • Partnerships & Supply chain ● In-house & outsourced technology • Road map in 4 years 2 Introduction As final task for this assignment we were asked to design an own product line. In order to do this properly we went through several exercises to gain enough information to be able to set a successful product on the market. The product we want to design is a bicycle. Along the way we discovered VANMOOF, who has kind of a similar vision as we have. Therefore we used a lot of their insights in our research. First we investigated the market. We needed to make a persona and state the needs, desires and problems this persona might face to find out what product it would need. The next step was to find out what the best way is to sell our product, how we could reach our users best. After that, It was useful for us to look into the competition we would face. That way we could make sure to add something new and different to the market, and not only be copying. Now we have some more background information, second up was a value proposition. We made a first concept description with help of the information we gathered during the market research. On the basis of this concept description we made a value ladder to see if every aspect of the concept made sense, if we could trace the functional specifications back to certain values.

    MONTAGUE BIKES montaguebikes.com Montague to Showcase Redesigned Folding Bicycle Frame at Interbike New DirectConnect System Delivers Increased Frame Stiffness and Superior Ride Quality CAMBRIDGE, MA – August 5, 2016 – Montague Bikes, the leader in full-size folding bikes, is proud to bring its newly redesigned full sized folding road and mountain bikes to the Interbike International Expo in Las Vegas September 21- 23. The 11 new bike models all feature the new patented DirectConnectTM folding system that provides increased frame stiffness and ride quality superior to other folding bikes on the market while allowing the bike to be folded in less than 20 seconds. The DirectConnect system builds upon their concentric seat tube design, which does not break the frame’s tubing to allow the bike to fold. The design, already considered the strongest folding frame on the market, is improved with a revolutionary latch that directly mates the two halves of the frame when unfolded. It removes the need for a quick release on the top tube and provides a larger clamping surface and load bearing area than their previous design. Also, Montague will be featuring its Eurobike award -winning RackStand which serves as a cargo rack and mud guard when the bike is in use, converts into a kickstand when parked, and allows the bike to stand upright when folded. Until now, the RackStand was only available on select Montague bike models. Beginning this fall it will be available for aftermarket sale. “We are constantly challenging ourselves to improve our designs,” said Montague Bikes President David Montague. “The new DirectConnect and RackStand technologies incorporated into this year’s bike models have helped to ensure the best ride quality available from a folding bike.” The 2016 Montague bike line-up includes six road and five mountain bikes ranging in price from $639.95 to $2,449.00, many of which will be on display at Eurobike including the brand new Allston.

    The Ultimate Commuter Bike The Montague Allston is a Full-Size Folding Bike on the Cutting Edge of Bicycle Tech CAMBRIDGE, MA – July, 2017 – Kiss those tiny wheels, greasy chains, and noisy derailleurs goodbye. Montague Bikes, America's leading maker of full-size folding bikes, has broken the mold with the all new Allston. You've seen small wheel folding bikes – those that seem to belong in the circus. Folding bikes have suffered that indignity for too long, and the Allston is here to prove good looks, performance, and portability can exist together. Instead of small wheels, the Allston is equipped with full-size road wheels that deliver a ride indistinguishable from other high performance bikes - even those that don't fold. It doesn't use a traditional derailleur like other bikes which can be noisy and require regular tuning. In fact, it doesn't even have a chain. In place is a sealed internal gear hub for shifting and a carbon belt that requires no oil, and will never rust - no matter how long it's in the rain. Luckily, this full-size bike doesn't need to be locked outside in the rain, in sight of bike thieves, because it folds to easily store in any closet or city apartment. It was designed from the ground up to deliver a combo of top-rated performance and unique portability to commuters. The cutting edge components and a folding design offer the perfect solution to those looking for a reliable, low maintenance bike that fits an on-the-go lifestyle.
