The Sierra Trails has both a twist and go throttle on the handle bars, like a motorcycle, and a pedal assist system.  The Pedal Assist System or PAS, senses how much effort the rider puts into pedaling, and uses the electric motor to add power and speed.  Just pedal and the electric motor will give you an increased feeling of power, and allows for increased range. You can also twist the throttle on the right hand grip and get the bike moving from a stop without pedaling.

The Trail Maker and Trail Climber uses a Lithium Ion Battery (LiFePO4) which is lighter and lasts for 3-5 years where the sealed lead acid battery lasts around 2 years and is heavier than its Lithium Ion counterpart.

  • decent electric bike

    Posted by Beth on 7th Aug 2014

    Have had this bike for few months now and it has worked well. However, it is a bit heavy, kinda wish I went for the lithium Ion bike since its lighter and has disc brakes. But other than the weight, this is a really fun bike and gets up some good speed, and good build quality.
