		Dahon Vitesse D7 Electric, Dahon Ciao D5 Electric

We have for some time now been of the opinion that what the two wheel market needs is a quality folding Electric Bike that can be used without a licence, Road tax or Insurance on the road. Until it was discontinued we stocked the Dahon Roo EL which sold for over £1,200.00. This was a very good machine but suffered from a few niggling problems at times mainly due to connections. The Sram Sparc system employed on the bike, being an internal 5 speed hub gear and motor combined was probably unnecessarily complicated for it’s own good and at only 16V it was not quite as powerful as many other motors now available, it came complete with a small NiMh battery pack which was very light but had limited capacity. The whole bike however was probably the lightest quality folding electric bike in the world.

We have fully taken on board in considering the electric folding market, that there must be a balance between being a marvellous showpiece of engineering and prohibitively expensive on the one hand, and on the other, deliberately pitching the price down to a level where the quality suffers seriously. We have therefore arrived at producing what we consider to be an ideal combination. We present these Dahon Models as ‘mid range’ in terms of the components, which for the average person, represents a good standard of engineering, and are confident that the models we offer can be broadly termed ‘quality folding electric bikes’

This has involved us in choosing appropriate comfortable and respected bikes, for this conversion we have chosen the hub-geared Dahon Ciao D5 which is well suited to the type of rider that invests in an electric bike. It benefits from a low step-through frame and is suitable for both Ladies and Gents to ride. We also build the Electric Dahon Vitesse D7 which has a 7-speed derailleur gear. The Vitesse has a straight frame and therefore not such a low step-thru, and is more popular with younger riders. The Ciao having an extremely low step-thru is popular with riders who have difficulty getting on and off of a normal bike. We have also sourced some quiet running intelligent brushless motors, battery units etc. that when fitted in our workshop are both pleasing to the eye and unobtrusive. When pedalling with the motor switched off on relatively level ground you would not realize that you are riding an electric bike, since the front wheel hub motor spins so freely.

The price of these models varies from £1299.99 - £1399.99 including delivery. This also includes lights, mudguards, stand, Cateye wireless computer, and a special rear carrier that houses and includes the battery pack, but still leaves room for panniers and top bag. The intelligent charger is also included.

The battery packs that we are now using have Lithium Panasonic Cells which are now widely accepted as being a very reliable, stable, and safe option. We have also noted in our product testing a vaste improvement since the earlier days of Lithium batteries, (when we rejected them and used NiMh batteries instead) concerning both the range and currently their more predictable behaviour, as they gradually become exhausted and ready for the next charge. Another bonus is that these batteries have a recharge expectancy of 700 - 1000 cycles, though of course we only have this figure from the manufacturer. We have not ridden a test model for 30,000 miles to find out yet !!

Front brushless hub motor and Rear mounted LiMn Battery for more balanced weight distribution. The Vitesse and Ciao Electric bikes are a joy to ride mainly thanks to the expertise of Dahon who manufacture the standard model and have 25 yrs of experience in the folding bike market. Our electric model is also easy to push along on it’s wheels when folded. This is achieved by leaving the saddle extended, tilting the folded bike to the point of balance, and it then requires very little effort to manoeuvre it around. The front and rear half of the bike are held together when folded by the Dahon Magnetix system.

We no longer build the Dawes Kingpin Electric (shown above), we have decided to promote the Dahon Brand itself for the electric versions.

	The motor responds progressively as the speed controller is twisted around up to the maximum permitted speed of 15 miles per hour. Both brake levers as a safety feature have switches to cut the motor immediately you brake regardless of the speed controller position. The big advantage of these systems is that when on the level you can ride the bike unassisted with the switch turned off and there is no drag from the motor The best policy is to inflate the tyres to at least 60 PSI to keep the rolling resistance to a minimum.

		It is of course possible to ride without pedalling at all, but this will reduce the milage considerably that the battery has to offer. The really great thing about electric bikes for those of you who need some help, is that it takes all the sweat and struggle out of climbing normal hills, and puts the fun back into cycling.

The Electric motor kits are professionally fitted by ourselves in our workshop. The wires into, and the aluminium control box itself, are sealed ourselves with silicon cement to prevent ingress of water. The Battery is locked into the carrier by a keyed switch that doubles as an on/off switch as well as the battery lock. The Battery can be removed for charging, or left in situ. if there is a powerpoint suitably positioned.

An intelligent charger is supplied with the bike which takes 4 - 6 hours to recharge the battery if it’s exhausted.

The bikes are sold with the usual warranty of one year on components and 5 years on the frame.

The Battery is now included with this 1 year parts warranty in common with some other manufacturers. (certain exclusions are applicable if the battery has been subject to abuse, or for example, dropped - they do not bounce too well) If used correctly the normal expected life of LiMn batteries is around 700 - 1000 charges.


	We do of course normally have a demonstrator for those who wish to visit our High Street shop.

	Important Customer Information


	For those of you who prefer a more personal service, we are always very happy to discuss the advantages of the various models to help quide you towards a bike that is suitable for your requirements and within your budget. We have a passion for folding bikes and their place in todays society for both the commuter and leisure cyclist alike. Please ring us if you need help or advice on 01666 822330

All Folding Bikes are thoroughly prepared and checked in the workshop in order to validate the warranties, this involves a thorough setup and adjustment of spokes, bearings, brakes, gears (stops and cable adjustment). The chainset and crank, handlebars and all nuts and bolts are checked for tightness and the pedals fitted. Finally the tyre pressures are set and the folding joints and all quick releases are lubricated and adjusted. After a brief test ride (mainly indoor) they are then carefully packed back into the original boxes using appropriate packaging, this means that the bikes when received and unfolded are ‘ready to ride’ . All 26” wheel Dahon bikes arrive in the UK in boxes with the frame unfolded but the bike partially dismantled. We have taken the decision that in order to properly achieve our highest aim and that of the responsible manufacturers with whom we liase, that we therefore, properly prepare then fold the completed bike with only the handlebar removed, it is therefore necessary for us to repackage the bike accordingly on account of it’s larger size when assembled.
