Description

The Ultra Light Assist forum is for exploring options and improvements to Ultra Light Assist (ULA) systems for otherwise human powered vehicles (HPVs).

Common reasons for ULA include assisting acceleration and adding boost for a pedaler to climb hills. These reasons may help make HPVs more palatable to a larger audience. People who are "too far" or subject to "hills too big" may consider ULA to make a cycling commute a reality.

ULAs are often considered for installation on delta or tadpole trikes. These trikes, sometimes called velos, often have fairings to improve aerodynamics and protect the rider from weather.

The ULA group is moderated and you must contact a moderator to be added to allow access to files or post comments. This level of security is regrettable but necessary to counter spammers. Thank you for your understanding.
