750 watt torque sensing mid-drive motor with 52v 728 watt hour battery. What does that mean? It means the motor is the maximum power US law allows, it senses the effort you are putting into pedaling and magnifies it. Mid-drive motors are located down by the pedals so the weight is low and centered on the bike. Unlike hub motors, mid motors get to use all of the gears you do so they can go fast in high gears and have power for climbing in low gears. The battery is high capacity and will take this heavy bike 30+ miles. If your ride includes hills or you just want to go further faster the Madsen is a great bike to electrify and this motor and battery combination are unsurpassed.


Instructions to electrify your Madsen are included. All parts needed to electrify your Madsen are included. Wires and cables are designed to fit your Madsen bike. This kit includes special tools to take off the bottom bracket and install the motor. Other common tools also required but not included.

The Madsen Cargo Bike is one of the most highly revered cargo bikes on the road.  It is affectionately called the 'bucket' bike.  And what a bucket!  With 4 seat belts and a carrying capacity of 650 lbs.  Whether you are hauling a bunch of kids and/or a weeks groceries it is fun, comfortable and perhaps its most liked feature is its stability.  With the small rear wheel to keep the center of gravity low and the cargo forward of the rear axle, this is one cargo bike you can just get on and ride and feel like you are in complete control.  With a solid steel frame, big bucket and heavy payload it takes some effort to peddle.  If you run into a hill of any size you have a problem.  The solution is a powerful motor and battery combination from Electrify Bike Company.  The Electrify Your Madsen Bike Kit provides pedal assist such that despite all of your load, it levels the hills and you feel like you are just pedaling a normal bike.  If you are too tired to pedal or you just need more power quickly there is a throttle too.

Most of the motors on factory cargo e-bikes are designed for the European market and European laws which provent e-bike motors from being more than 350 watts.  The Electrify Your Madsen motor is designed for the US market which allows motors up to 750 watts.  That is exactly the power the 750w torque sensing TSDZ2 motor we customize for your Madsen is designed to put out.

Electrify Bike's Madsen mid-drive motor kit is the perfect match to take a nice cargo bike and make it great.  It bolts into the bottom bracket and gets to use all of the gears you use.  The battery holds a whopping 728 watt hours of capacity.  That's like having a tank and a half.  This battery will carry you from 25 to 40 miles on the Madsen depending on how much motor assist you are asking it for.

This is the kit to get if you want to feel like you are pedaling with super powers. With the torque sensing mid-drive motor you can dial in the level of assist you want and at each level the motor assist will be proportional to how hard you pedal. If you have long steep hills or like the idea of torque sensing peddle assist, get the Electrify Your Madsen Mid-drive Motor Kit.
