Electric bikes

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

We carry complete Electric bikes from Giant & Minneapolis Electric Bike Company....

We also custom build Electric assist bicycles using these kits for you.....

  • 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 integrating a Marin Novato, a Rock Shox I-ride suspension fork and suspension seatpost, and a Bionx 350L 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.

     

     
  • Electric Bicycle with Wilderness Energy motor.

    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


    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.

  • GIANT TWIST FREEDOM DX ELECTRIC ASSIST BICYCLE

    The all-new Twist Freedom DX is no ordinary bike. And it’s not an electric bike. It’s a new type of hybrid that seamlessly combines battery power with your own pedal power to help you ride farther, faster, and with less effort. The Giant Twist DX paves the way to a fitter you, and a brighter, greener future. At Tonka Cycle & Ski we are excited to offer the Twist DX to the twin cities area.GIANT TWIST FREEDOM DX AT TONKA CYCLE & SKI

    For modern aesthetes, aspiring eco-enthusiastic commuters and folks who crave the fun of bike riding without doing much work, Giant's Twist Freedom DX hits the mark. A true hybrid, the Twist has no throttle. It relies on both pedal power and an unobtrusive, yet sturdy 300-watt motor to set you on your way. If you don't pedal, there's no power and that's just the way Giant (one of the world's, ahem, giant bike makers) thinks it ought to be. And having built a 125,000-square-foot factory dedicated solely to developing and manufacturing its own pedal-assist bikes, the company's commitment to the technology cannot be denied.

    Owing to the company's manufacturing expertise, the fit and finish on the Twist's aluminum frame is impressive. And the all-important riding experience is incredibly smooth especially with the internal 7-speed gearing. Older versions of this technology skewed a bit towards the herky-jerky because the motor wasn't smart enough to modulate the power input — but now that has changed. Nestled neatly within a polycarbonate case in front of the rear wheel is Giant's I2 Driver, the brains of this outfit. It monitors and modulates the motor's output in concert with a rider's pedal input to provide a steady, consistent ride. The pedal-assist drive system has three modes or power-assist settings — Economy, Normal and Sport — which deliver an increasing amount of power and diminish a rider's effort as you move from the Econ setting up to Sport

     Features

    — Lightweight men’s or ladies geometry aluminum frame

    — 2 Lithium Ion battery Energy Packs for extend range

    — Integrated pannier system

At Tonka Cycle & Ski carry a great assortment of what we feel are the  best Electric Bikes.

If you're in the Minneapolis area stop bye our 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 by installing a Bionx or Wilderness Energy kit to a bike of your choice.
