Other Reviews of Greenspeed Trikes

The GT3

"Any way you cut it, the GT3 is a great addition to the already rich tadpole trike market."
from Bentrideronline.com Editor's Choice Trike of the Year 2004 review

"... the GT3 can be a capable tourer or utility trike, as well as a fun machine for weekend blasts in the country."

"The Greenspeed GT3 is an awesome pedalling machine. It's supremely comfortable, copes with hills that would require the fittest of riders on a bicycle, and is beautifully built with quality components."
from Julian Edgar's review for Australian Cyclist January 2006

The X5

"It’s... the most stable trike I’ve ever ridden at high speed. The X5 was literally hands off at 70 km/h. Rocketing through the corners on my favorite long descent was more fun on the X5 that I remember it being on anything else I’ve tried."
from the 2005 X5 review by Bryan J. Ball, Managing Editor Bentrideronline.com

Useful Cycling Reference Books

Bicycling Science, third edition by David Wilson is a fantastic resource. He quantifies every aspect of cycling, from human power generation rates, to tyre rolling resistance, to aerodynamics and powertrain efficencies and more. If you are at all serious about knowing the hard science behind these phenomena, to compare or improve design or operation of your HPV this is book is essential reading and reference.

Barnett's Manual, fifth edition by John Barnett is four volumes of no-holds-barred bicycle mechanics, maintenance and repair. While there's no trike-specific content, almost all trike components are standard bike parts too, and John Barnett walks you through the steps of derailleur setup, brake adjustment and wheel trueing and more, with advice on tool selection and alternative steps as well. This is the workshop manual!

Bicycling Medicine by Arnie Baker is to the cycling engine what Wilson and Barnett are to the vehicle. The subtitle "Nutrition, Physiology and Injury Prevention and Treatment for Riders of All Levels" sums it up. It's easy to read but in-depth enough to hold a lot of useful advice and information about making your trike (and bike) engine run better .

These are all through amazon.com, which we find very useful too.

Medical Research Pertaining to Recumbent Cycling

Following are some links that discuss some of the physiological aspects of cycling in general and recumbents in specific. Note that in some cases listed a "recumbent bike" is in fact a recumbent stationary exercise bike, and as such the conclusions drawn may not totally match the reality of on-road cycling. Nevertheless, the broad direction of the conclusion should hold.

The recumbent position may be beneficial in reducing loads on the anterior cruciate ligament in the knee while cycling

Cycling on a tandem machine produces lower physiological stress than a single rider machine

Recumbent cycles may be more beneficial than conventional cycles for some diabetic riders

Is there any difference in penile blood flow during cycling in an upright versus a reclining position?

"The Vicious Cycling" - a discussion of some of the urological issues of upright cyclists that recumbents avoid
