Greenspeed Magnum Big Wheel (BW)

Greater Stability with Big Wheels
Normally trikes with large rear wheels are unstable due to problems with rear wheel flex and rear end instability. Thus we have made special GS rear hubs with a much wider flange spacing than normal, which has resulted in a 26” wheel with more lateral stiffness than a 20” wheel! Plus we have increased the section size of the rear forks. Thus with the longer wheelbase, the Magnum BW is even more stable at high speed than the Magnum SD.

For people who want even larger wheels than 26”, the Magnum BW frame has been built to accept a 29 inch rear wheel. Plus the rear forks are wide enough to accept a 4 inch wide tyre, and 4” wide wheels may be fitted, with 20 x 4 on the front, and 24 x 4 on the rear, for use on sand. For use on sand we recommend the use of an internally geared hub like the Nu Vinci or the Rohloff, and the frame is fitted with Rohloff OEM dropouts and extra cable guides.

Big Wheel and Gearing
The large 26” rear wheel of the Magnum BW has a number of advantages over the 20” of the Magnum SD. Instead of needing the special 52/42/30 crankset of the Magnum SD, the Magnum BW uses the standard Shimano Sora 50/39/30 crankset so replacements will be easy to get. Another advantage is the larger wheel lifts the rear derailleur and chain further from the ground, so that the trike is more suited to off road use. Plus, as the 26” wheel is the most common size bike wheel, there are a greater selection of tires available. Finally, the larger rear wheel just LOOKS better than having the same size wheels all round.
