    Many recumbent trikes have “direct” (tiller type) steering, where for cheapness, the handle bars are clamped directly onto the kingpins, without any intermediate linkage, and bars have to be moved in the opposite direction to which you are going, with the weaker muscles of your arms. Whereas the GreenSpeed “Crossover” steering was invented by GreenSpeed to provide control with your bicep muscles, thus the steering is much easier and more intuitive to use. Furthermore, unlike other types of “indirect” trike steering, the GS Crossover steering provides superior Ackermann compensation, and a smaller turning circle, due to the fact that the steering rods cross over from one side to the other.

    GreenSpeed as well as other forward thinking human powered vehicle companies have discovered that the rolling resistance of bicycle tyres does not increase until a camber angle of 10 degrees is reached, thus to improve stability without making the trike wider, to counteract tyre distortion while cornering, and to reduce rolling resistance in the turns, the Magnum front wheels have 5 degrees of negative camber. Plus on tight turns the steering geometry changes the camber of the inside wheel from negative to positive, again to reduce rolling resistance and tire scrub in the turns. Plus by swapping the tires from side to side ½ way through their life, more life can be obtained than if they were ran vertically.

    Unlike a bike, the front wheels of a trike are offset some distance from the centre line of the machine. Thus, applying one front wheel brake, as when hand signalling for a turn, while braking, will tend to steer the trike in that direction. So, to compensate for this, the Magnum has Negative Scrub Radius steering geometry, whereby the brake reaction steers the trike in the opposite direction to which the braked wheel is pulling it. This happens so subtly that all the rider notices is that the trike continues in a straight line, when only one front brake is used. However, for emergency braking both brakes should be used, as this will double the braking power.

    Best oversize trike

    Rating:
    Pros:
    Cons:
    I am 390 Lbs and this is the only trike that I have found that fit my body and can handle my weight. On other trike I tried as soon as I turn the handlebars the handlebars were hitting the side of my legs and limiting me from turning as sharp as I wanted. The Magnum XL is truly a trike for an XL person. The frame is wide, handlebar is wider, seat is wider and come with a higher seat and weight capacity. The front brakes are oversize to help with stopping and the tire wider to help improve the ride quality. The wheel are heavier duty than any other trike I could find. My trike fold easily and is light weight. If you are an oversize person the Magnum XL is the trike to get.
