  • The motor works to assist your pedal power. It will turn on to the power level that you select on the display as soon as you start pedaling. When you stop pedaling, the motor shuts off. You can also purchase a handlebar mounted throttle to engage the motor if you'd like to cruise around without pedaling.

    The Swift's motor will assist you up to 20mph.

    The battery life varies based on numerous factors (the power level used, the rider’s weight, the amount of pedal assistance, cargo, terrain, wind, etc). Even a cargo-bike rider using full power can expect at least 15 miles to a charge, and you get over 50 miles on a standard bike using lower power settings and pedaling normally. Most folks report a battery range between 20 and 30 miles.

    The total system weighs 13.6 lbs, but it replaces your front wheel, which weighs about 2 lbs. So it will add 11-12 lbs to your bike, and carry WAY more than what it adds!

    The Swift requires a bike with:

    1. 100mm front dropout spacing (almost all bike have this)
    2. Enough room to mount the battery in the main frame triangle
    3. Water bottle mounts on the downtube
    4. Disc or rim brakes
    If you have any questions about whether your bike meets these criteria, call us at (206) 588-6546, or send an email to We’d love to help!


    We suggest having this system professionally installed. The cost for this is $159, and generally $150-250 at most local bike shops comfortable with electric assist installation (we'd be happy to reach out to your local shop and verify that they're comfortable performing this work). If you'd like to install it yourself, please contact us for instructions.

    The entire system comes with a 2-year manufacturer's warranty. Essentially, that means that any damage not caused by an accident or misuse is covered. See the full warranty here.

    It really comes down to how well you, the battery’s owner, care for it. With that said, you can expect a full 400 cycles with the standard charger before the battery life drops to 80% of its original capacity. But with the variable charger, you can extend that number to 1,000 cycles or more. Find out how here. We warranty the battery for 2 years with some stipulations (see warranty section for more information).

    From completely flat, the battery takes about 7 hours to fully charge. Want faster charging speeds? Check out the variable charger!

    Nope. But don’t leave it plugged in for too long (24 hours or more). It keeps the cells from dropping down to their resting voltage and prematurely ages the pack.

    No! Actually, it's best to not completely discharge the battery. We suggest you simply recharge the battery overnight after riding, regardless of whether it's completely dead or not.
