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.
the seat may look simple, it is actually the most comfortable on
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.
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
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.

trikes may differ slightly in specification and equipment
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.
