Electric bikes

We Carry Electric Bike kits from Wilderness Energy & Bionx...

We have built this Electric Assist Bicycle up by putting together a Wilderness Energy kit and a Giant Tran-Sport DX as the base bicycle; it is a heavy duty 26" wheel bike with front & rear racks and a multi position handlebar. We then upgrade the rear wheel for added strength and add a Wilderness Energy front wheel drive elictric bike kit. Next we add a cateye computer and rear flashing light, You now have a great Electric Bicycle that you can also pedal, it has a range of about 20 miles and can easily manage speeds up to 20 MPH. The BEST part is we can sell you this complete bike for only $1100.00

  • Electric Bicycle with Wilderness Energy motor.


    The complete motorized Electric Bike... Come and take it for a test ride....

     


    The Wilderness Energy brushless 600watt front hub electric motor. As a wilderness energy dealer we also offer just the motor kit that we can add to many other bikes.

     


    The comfortable multi position handlebar, drive throtle on right bar, computer to keep track of your trips, & bell with compass.

     


    36 volt battery pack complete with plug in charger mounts to the heavy duty rear rack.

  • Electric bicycle with Bionx assist motor

    The Electric Bicycle kits from Bionx are a step above the others.... With the Bicycle pictured below we have built what we feel is one of the best electric assist bikes by intigrating a Marin Muir Woods 29er, a Rock Shox suspension fork and a Bionx 350 motor kit.

    Allows long distance riding with minimum level of fatigue; Up to 65 miles

    Adds to your pedal strokes and eliminates dead spots.

    Can be used as training for the faster cyclists due to the generative mode.

    Can be used as an interior and exterior workout machine.

    Gives the sensation of riding with a super light bike (level 2 eliminates the weight of the bike).

    The motor-wheel is quiet and requires no maintenance.

    Being light, it can be taken anywhere; Whole system weighs 14-17 lbs.

    Can be easily installed on YOUR bike.

    The battery can be recharged while braking or going downhill.

    Allows you to defy the hills, the wind, and even a faster cyclist.

    Is a great mode of transportation to get to work.

    High performance direct drive generative wheel motor (gearless - brushless).

    Equipped with a magnetic field drive technology, the external magnets (wheel) turn whereas the stator is not moving.  Therefore no friction inside the motor and thus no wear.

    Using a microprocessor, the motor is measuring your thrusting power (through chain torque) and compensates for your weakest leg, therefore insuring a smooth progression.

    With the console and throttle you have complete control on the electric assist and self generating functions.

    The battery is an important element for the autonomy and the weight of the bicycle. It is for this reason that Bionx utilizes NiMH (Nickel Metal Hydride) and  Li-Mn (Lithium- Manganese) batteries, each offering their own strengths an advantages. The battery makes it possible to have an excellent autonomy without adding too much weight to the bicycle.

    Ni-Mh Advantages: - Good energetic density (60-80 Wh/kg) - strong  - safe  - flexible

    Li-Mn Advantages: - Very high energetic density (100-200 Wh/kg) - Lighter than the Ni-Mh

    In addition to the battery cells, the BionX battery also includes electronic compoments that allow it to communicate with the other BionX parts (motor and comand console). 

    ASSISTANCE
    Bionx is ideal for riders that want to ride longer and keep up with the pack or those that want help up hills and against the wind. Four assistance levels amplify the cyclist’effort by 25%, 50%, 100% or 300%, allowing the cyclist to ride faster while giving the same effort (or ride at the same speed with less effort). Each assistance level is proportional to the rider’s effort.

    GENERATION
    Bionx offers four levels of power generation. Regenerative braking activates when the rear handbrake is used. It is possible to charge the Bionx battery pack by pedaling against motor resistance. Generation mode makes it harder to pedal so its often used when going downhill. Please note that the generative mode does not replace the existing brakes, but
    considerably increases braking quality, especially on extended downhill runs.

     

     

At Tonka Cycle & Ski we have put together what we feel are the  best Electric Bikes.

If your in the Minneapolis area stop by our bicycle shop in Minnetonka to take these Electric Bicycles for a test ride..... its a blast.

We can also build you up a custom Electric assist bicycle of your choice or install an electric motor to your present bike.
