at last – no compromises!


Many people have said that it is not possible to build a 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 breaks the mould in trike design! No longer is it necessary to agonize between the choice of a high seat trike for off road, or a low seat trike for on road, suspension or non-suspension, disc brakes or drum brakes, or a heavy, low performance trike to take your weight.


The Magnum 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 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 Magnum 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.

Disc brakes normally have superior stopping power to drums brakes, but disc brakes make it harder to take the wheels off and on. They are also difficult to adjust, the pads wear faster, and they cause more drag. So the Magnum is the 1st trike to use the new, larger 90 mm Sturmey Archer (S.A.) drum brakes. Plus they are used with the matching S.A. brake levers, which are longer, and have more leverage. Thus the performance is as good as the disc brakes without all the disadvantages. Then as a bonus, they come with a press button quick release. So if you need to make the trike smaller, to place it in your car, taking the wheels off is effortless! So with the central frame hinge, and the quick release wheels, the Magnum will pack down in to a box (33 x 29 x 18") not much larger than its smaller brother, the Greenspeed GT1.

The smaller 16 inch wheeled GT trikes have been limited to a rider weight of 265 lbs. Whereas the Magnum, with its larger diameter frame tubes, has rider weight limit of a whopping 400 lbs!  Yet thanks to the high strength 7005 aluminium tubing, the weight of the whole trike is only 2 lbs more than the GT1, at 42 lbs.  So you can be sure that the trike will be strong enough to cope with all your adventures.


In keeping with the heavy duty nature of the Magnum, a new luggage rack which is rated 88lbs has been designed and produced especially for the Magnum, and has passed the 100,000 cycle vibration test at this loading. Please check out the rack and other accessories HERE.


The Magnums have proved to be our fastest selling trike yet, and we have been hard pressed to keep up with the demand, so to avoid disappointment, please place your order with our DEALERS well before you need to buy one, if possible.

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.
