ride 2 recovery triple amputee trike lasher (1)

Any cyclist that has ever had an injury that has kept them off the bike, knows the feeling of frustration that comes from not being able to ride. However, Timothy Brown is proof that seemingly no matter how bad the injury is, where there is a will, there’s a way. As a triple amputee, Timothy is crushing it on his adaptive recumbent trike thanks to Ride 2 Recovery – a nonprofit doing some great things by helping wounded veterans get rolling again. We recently had a chance to check out Matt DeWitt’s radical custom Diamondback Sortie that was also built by R2R, and this trike is just as awe inspiring.

Just how does a Triple amputee ride a bike? Check out the details next.

Starting its life as a Lasher Sport full suspension hand cycle, the offroad trike uses three Fox Float X CTD shocks to keep the wheels glued to the ground.

If that wasn’t enough radness, the trike shifts with an adapted Shimano Di2 drivetrain. Thanks to the push button modular nature of the Di2 system, it makes a great option for bikes like this where a traditional shifter simply won’t work. While DeWitt’s bike used large top tube pads as shift buttons that he hit with his knees, Timothy uses two Di2 climbing shifters that he is able to use with his right leg residual limb. Not only is the limb able to shift, Timothy also uses it to activate the rear brakes – two Tektro hydraulic disc brakes activated by one lever. Under the seat there is a splitter where the single hose from the lever is split into two for each brake.

The front brake or brakes are equally interesting with two calipers clamping the same rotor. The main brake is an Avid Code which should provide massive stopping power. The other caliper is BB7 mechanical caliper that functions as a parking brake through the Dia-compe lever at the top.

Braking is all controlled by Timothy’s left hand while his right prosthetic arm attaches to the crank in order to pedal.

At the seat Timothy is held in place with a lap belt and is able to stay hydrated with a flexible hydration hose over his right shoulder.

We missed the R2R Honor ride arrival at Outdoor Demo, but this photo of Tim was posted to the R2R Facebook page by Rick Bruder.

Thanks to R2R founder John Wordin, equipment director Scott Moro, and a number of other R2R team members, Timothy was able to ride his trike for the first time on the Interbike Honor ride – a 25 mile ride from Mandalay Bay to the Outdoor Demo.

Keep up the good work!




  1. Agreed, this is amazing. As the technology develops, bikes/trikes like these will become more common. I hope one day to run across one of these beasts while out of the trails!

  2. These things were amazing to see in action. The guys piloting them were stoked to get into the dirt and play around.
    Did you guys notice the Ultegra Rear Derailleur is a 6770 body with and SGS long cage and XTR 11-36 cassette.

  3. A bike like this seems like a good candidate for the sequential shifting Fairwheel did a while back, where there is just a single upshift and single downshift button, and the front and rear derailleurs work in concert to provide even gearing (i think it was 14 different ratios). I’d love it if shimano added the sequential option to the e-tube project, you can have a flatbar bike with just one climbing pod, or a tt/tri bike with the one button shifters and still have a full gearing range in the aerobars

  4. Nick, there was only one shifter on that hand cycle. The guy piloting it was a triple amputee, so another shifter wasn’t an option. It was really an awesome sight to see being used in real life. I’m sure there was some stuff in there that is “skunk works” or full on one off from the manufacturers.

  5. Kerry,

    There are two shifters on that bike. They are both DI2 and he shifts with his leg. Tim is a great guy. I hope to ride with him again
