Whether you’re using your own power or the electric assist power, this bike can take you wherever it is you’re going with strength, comfort, and style.


Inactivity is a much more serious health issue than obesity, but deciding to get moving when you’re seriously overweight is not simply because the tools needed are not available.  Introducing our best-selling bicycle for big riders, A New Leaf 3.0, now upgraded to an e-bike!  This strong, comfortable bike is charged up with a super-powerful motor and battery so that even the heaviest riders can get up steep hills and keep moving.  With this bike, lack of fitness will no longer stop you from getting into cycling.


A New Leaf 3.0 is an amazing bike by itself. It has a custom chromoly steel frame and front fork, forged alloy shaft, and double bolted seat post. Its pedals are made with a forged alloy platform and a chromoly spindle, and are perfect to accommodate bigger riders. Wheels include spokes made of professional quality stainless steel; extra wide, double wall alloy rims; wide tires with high thread count, and inner tubes with Slime sealant which repeatedly seals punctures like magic!


A New Leaf 3.0’s 8-speed internal gear system allows for plenty of range and it means no stress for you. Since the gears are enclosed in a hub, you will no longer have problems with chains falling off.  You can shift gears in any position—while pedalling, while cruising, or from a complete stop—nothing to coordinate here. The internal gears will make your every pedal cycle count. Not needing to oil your chain after rides also means it’s zero maintenance, another way it makes it easy to stay healthy and keep up with all the demands on your time.


To create the magic of the New Leaf 3.0 e-bike, we added a 750 watt* Bafang mid-drive motor as well as a 48 Volt, 17.5 Amp hour battery. Bafang has been creating complete systems for electric bicycles for more than 10 years. The motor on this bike is high-performing, lightweight, quiet, fast, hill-climbing, and well-engineered. Superior to hub motors, the mid drive motor kit feels just like a normal bike when pedaling since it can completely freewheel. Its position in the lower center of the bike helps balance the weight distribution. The motor includes pedal assist sensors (PAS), so you can choose the power level of motor assistance that you would like while pedaling. Also, you can always overpower your designated PAS level with your throttle in order to achieve your desired speed and power.


The battery included with this bike is a 48-volt battery with 17.5 Amp hours.  Think of volts as horsepower.  A 48 Volt battery is a seriously high voltage for an electric assist bike, which is often necessary because we’re moving some serious cargo.  The Amp-hours are kind of like the fuel tank for your bike.  17.5 Amp hours provides plenty of reserve power to keep the bike going.


A New Leaf 3.0 E-bike is styled a little like a mountain bike, built like a truck, and has the strength and comfort of a Zize Bike–on steroids!


A New Leaf 3.0 E-bike gives you an easy way to get your health back and have a blast doing it!

* In the past, we’ve sold this bike with a 1000 watt motor. The problem was that it was so strong that the bike was no longer classifiable as an e-bike. To remedy this, we have upgraded the controller of the 750 W motor to 1000W output. The shell still reads 750 W.
