The Dimension Edge is an American roller drive cyclemotor that fits over the rear wheel. The Standard model has a 35cc two-stroke engine of 2bhp. It follows the common American practice of using an off-the-shelf industrial engine, which is built into the cyclemotor assembly It has what is described as a ‘spring wishbone strut suspension’ on either side of the unit, which bolts on either side of tha wheel spindle. The unit is sold with two rollers; one is intended for all weather/all terrain use, the other is a plain polyurethane one for dry road use. Different diameter rollers are available as optional extras to enable the rider to alter the gearing of the unit. The tank holds 3 cups (sic) of petroil, whish is claimed to give a range of 40 miles but a larger tank, ‘for all day use’ is also available. The unit has a speed range of 3 to 35mph. Extensive use is made of aluminium in the construction of the unit, which weighs 10½lb.
A larger unit, of unspecified cubic capacity, is available; this produces 2.9bhp. Various optional anodised finishes and colours are avialable for the aluminium parts—the cyclemotor as fashion statement! The Dimension Edge can be obtained as a complete autocycle, fitted to a 20" wheel Dahon folding bicycle. The engine is claimed to meet current US emission standards and, moreover, to be almost completely recyclable—not that that would be of interest to NACC members!
