Triker Bob (Greenspeed)

Bob Devlin has been a Greenspeed enthusiast for many years, and proves that these trikes from Australia truly hold up to the long haul on freedom’s road. Bob and his wife Kathryn live in Jackson, California, in the foothills of the Sierra Nevada Range. Bob owns an 18,000 sq. ft. fitness center in northern California (New York Fitness), but he wishes to retire from the business, so here is an opportunity for anyone wishing to get into this line of work. His fitness and health pay big dividends when it comes time to go trike exploring!

Bob Devlin GreenspeedThis is how Bob carries the reliable Greenspeed on his petroleum powered wheels. Here is his explanation of this cost-effective custom trike carrier:

I travel from our house in Jackson (Sierra Nevada foothills) to Tucson quite often and quite easily transport the trike on top of our Subaru Impreza. REI quoted me $800 for a bike rack so opted to buy a standard luggage rack and see if I could mount the trike. See picture on my trike (seat is in the trunk) just rolled up on top of the car and secured with bungee cords on the side wheels and a U-Lock (and bungee cord) in the middle. I zip on a few plastic ties for extra protection. Works great though at first it made a wind sound which I cured by wrapping some tape around the front railing.

January 2016 Update


Mine is a Bionx S Series with a DV-48V /11.6Ah/555Wh down tube battery (placed on my rear rack) with an S series hub motor with High Torque (HT) and 350W. This was put on my GT-1 Greenspeed with 16” wheels.


Extra boost when you need it (thru intersections, up steep hills, passing up some hotshot that zoomed past you, etc) by using the throttle.

Adds weight to the rear wheel for much better transaction (especially on my Greenspeed as its back wheel spins easily on sand or gravel).

For long uphills, engaging the assist doesn’t pedal for you but adds to your ability to increase your speed. The harder you pedal, the more it helps.

Saves my knees. There are frequent times when I come across a sudden hill and it takes extra pressure on my knees to push over (not enough time to shift down). The throttle allows you to keep spinning instead of forcing yourself over the hills. It’s fun, too.

Using the regenerative option on downhills, I not only recharge the battery but it allows me to keep pedaling where I would just have to coast without it. So I get more exercise and spinning.


Cost. With installation it was $2,600. You can buy a pretty nice entire trike for that.

Weight. Battery adds about 10 lbs and new hub 7.7 lbs. Lifting the rear end to drag the trike is much more of a challenge. Surprisingly, it has not seemed to slow me down much when I pedal without the assist.

Scorn from some cycle purists. One guy called me a “cheater”.


This battery has enough juice to provide significant help on long trips. So far I have gone 65 miles and it had charge left. It all depends on how much you actually use it, of course.
