    Greenspeed Magnum may be the perfect do everything trike.

    Many people have said that 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 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 aluminum 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 tire 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 11-32 cassette combined with the 52/42/30 triple crank-set gives a wide range of gears, from 19" in bottom to 91" in top gear – a range of 479%! 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 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 aluminum 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.

    The one that fits

    review-star review-star review-star review-star review-star
    <p>The Magnum is perfect of larger people. I tried a number of different trike and many seamed to be just two narrow for me. For me the problem was on many trikes when I go to turn the handle bars would not be wide enough and would be hitting my legs. The Magnum is simply a wide trike with adjustable handlebars for width and angle, problem solved. I also appreciated that Greenspeed made and extra large seat on the Magnum for my extra large back side. I like that Greenspeed also use a larger brake to give better stopping as well. All the components are very good quality and I have been very pleased with there performance. The Magnum is made of lightweight aluminum but has a 400 Lbs weight capacity which seams to be the best of both worlds. The Magnum has extra strong double wall rims for extra durability and stainless steel spokes that will not rust. The Magnum can be easily transported by removing the seat with two quick release levers and folding the trike in half. The trike folds easily by using the quick release in the center of the frame and folding the rear of the trike over the front of the trike.</p>

    More Comfortable

    <p>I test road this and a few other trikes. I found this one more comfortable. The other trikes were too narrow making it hard to steer. It is higher from the ground, so I can get on and off from it easier. I enjoy longer rides now. I Just got the hang of the shifting.</p>

    Just what I was looking for

    review-star review-star review-star review-star review-star
    <p>I am a large man (400 Lbs) with bad knees and bad back. The Greenspeed Magnum really stood out for me as the trike to buy. What attracted me to the Magnum was a number of things first being the weight limit. The Magnum has the highest weight limit on the market for a recumbent trike. There are some other trike that are built for larger people but just not equal to the Magnum. The second thing that the Magnum offered was the adjustable seat height. I needed the seat all the way up because it is difficult for me to get out of the seat. With the higher seat height than other trike I can get out without any help or to much struggling. Third is the seat just fits my back nicely. The seat is contoured to fit my low back and it uses shock cords with a lot of eyelets for my weight. Other features that I liked were the heavy duty Sturmey Archeer Drum Brakes and heavy duty alloy rims. The Magnum came with Big Apple tires which gives the trike a smoother ride. I did add tires lines to the tires so I would be less likely to get a flat tire. Being I am very large I wanted the strongest wheels I could find. The Magnum came stock with three double wall rims and three twenty inch wheels. I wanted the smaller twenty inch rear wheel because it is quite a bit stronger than the twenty six inch wheels used on other trikes. Another advantage I like about the three twenty inch wheels is that I only have to carry one extra inter tube rather than two. The folding feature of the frame was not important for me beings I drive a pick up truck but would be a nice thing to have if someday I change vehicles to say a sport utility.</p>
