Greenspeed Magnum Folding Recumbent Trike

Many people have said that it is not possible to build a recumbent trike which is suitable for road as well as off road. Others have said, you must have suspension to give a smooth ride. However, this increases the weight, adds complication, and cost. 

Well, the Greenspeed Magnum folding recumbent trike breaks the mold in recumbent trike design! No longer is it necessary to agonize between the choice of a high seat recumbent trike for off road, or a low seat recumbnt trike for on road, suspension or non-suspension, disc brakes or drum brakes, or a heavy, low performance trike to take your weight. The Greenspeed Magnum Folding Recumbent Trike is the 1st recumbent trike to have a seat which is adjustable for height. Plus it is adjustable for angle as well. The seat height is adjustable from 12” to 17” and both adjustments are with Quick Release levers. Thus the rider can choose the seat height to suit ease of entry and exit, the riding conditions, and personal preference – low for speed and high for visibility in traffic. Some riders may find they need the seat high at first to help get them on and off the trike. Later as they become fitter and loose weight, they might find they can lower the seat and take advantage of the lower centre of gravity. This gives better cornering and road holding. Wind tunnel tests show that the lower seat is also 2 mph faster at 25 mph.

While the seat may look simple, it is actually the most comfortable on the market. First of all, the seat cover is completely open weave. This allows cooling to the back, and does not hold water if it rains. Then the curves were designed by a chiropractor to give proper support to both the lumbar and the shoulders. Secondly the shock cord lacing provides a good fit to your back, plus it provides suspension for insulation from road shock. Suspension is also provided by the Schwalbe “Big Apple” balloon tyres which give both a low rolling resistance and a comfortable ride. The third secret in the Greenspeed recumbent trike ride is the frame. Normally aluminium frames give a hard ride. However, each tube on the Magnum was carefully selected to give the same good ride characteristics as the Cro Mo frames. Thus by just adjusting the tyre pressures, the trike is equally at home on rough roads and smooth roads.

Now for off road use, you need a high ground clearance, and low gears, yet for road use you need high gears, and good road holding. The Greenspeed Magnum Trike has a massive 5” of ground clearance, yet with the seat low, and the cambered wheels it has outstanding road holding. Plus the 11-34 cassette combined with the 52/42/30 triple crank-set gives a wide range of gears, from 18” in bottom to 95” in top gear – a range of 527%! So you can easily go fast or slow.

Available in Red, Blue, Yellow, and Green.

* with crank extension at max.

** the maximum X-seam can be extended to 52" with use of an Extra Long, 475 mm crank extension, (12" Max mark) available from dealers. Also please note that the maximum and minimum will vary with the seat angle about 1" from the mid figures given between having the seat angled right back to having it right forward. Plus to achieve the shortest measurement, 2" will need to be removed from the end of the standard 425 mm black crank extension with the 10" Max. mark. A small amount of increase in the maximum can be obtained with longer cranks, and a small amount of reduction in the minimum can be obtained with shorter cranks. Early (2012) Magnums had 375 mm crank extensions with a 8" max. mark.
