Hydraulic Disc Brakes

Don’t settle for cheap mechanical disc brakes. A powerful bike should have the most powerful brakes to keep your safety a priority. Hydraulic brakes are stronger, more reliable and can help you steer clear of danger when you need it most.

Shimano Alivio 9 Speed Drivetrain

This 9 speed drivetrain lets the mid motor shine and apply it’s torque over 9 different gear ratios to maximize acceleration, hill climbing and top speed. The 11-34T cassette has a wide range and is built to last.

M600 Mid Motor

The M600 is the most advanced and powerful motor of it's kind on the market. Beautifically compact and packing a whopping 500W and 120Nm of torque, this workhorse is a serious performer. Using the bikes gears, it achieves optimum hill climbing, range, and speed.

Hidden Gear Sensor

Thanks to this hidden sensor, you can shift smooth every time. When you shift, the sensor will reduce motor power for just long enough to transition butter smooth into your next gear. Say goodbye to gear crunching and prolong the life of your drivetrain.

Quick Release Thru-Axle

Other bikes use toothpick sized skewers to keep the wheels on. This can save costs - but with a single failure point wheels can release while riding - a dangerous situation. Instead we invest in beefy thru-axles with redundant failure points. They’re over engineered to keep you safe and happy. The thickness of the thru-axles make them more durable and provide a more stable ride at all speeds.

In Frame Lithium Battery

We've upgraded our batteries from 36V to 48V giving you even more range and power! We sourced the highest capacity cells in the world, the same ones used in the Tesla Model S for this. Charging time is 3 hours for the 10.4AH battery, and 4.5 hours for the 13.6AH battery.

Minimal LCD Display

Like a cockpit for your bike, see how fast you're going, how far you've ridden, average speed and battery life. Plug in a USB cable into the USB port, turn the LCD screen on and you can charge your phone on the go.

Cruise Throttle (Optional)

Don’t want to pedal? Just hit the throttle above 6mph and the powerful 500W mid motor will propel you through the city with no effort at all.

The California Standard

Electric Bicycles are defined by the California Vehicle Code.

New legislation became effective in January 2016. The current regulations define an “electric bicycle” as: a bicycle equipped with fully operable pedals and an electric motor of less than 750 watts, separated into three classes:

1. A "class 1 electric bicycle,” or “low-speed pedal-assisted electric bicycle,” is a bicycle equipped with a motor that provides assistance only when the rider is pedaling, and that ceases to provide assistance when the bicycle reaches the speed of 20 miles per hour.

2. A "class 2 electric bicycle,” or “low-speed throttle-assisted electric bicycle,” is a bicycle equipped with a motor that may be used exclusively to propel the bicycle, and that is not capable of providing assistance when the bicycle reaches the speed of 20 miles per hour.

3. A "class 3 electric bicycle,” or “speed pedal-assisted electric bicycle,” is a bicycle equipped with a motor that provides assistance only when the rider is pedaling, (no throttle) and that ceases to provide assistance when the bicycle reaches the speed of 28 miles per hour and equipped with a speedometer.

Local government ordinances are allowed to permit or ban any class of electric bicycles on dedicated bicycle paths and trails, with Class 1 & 2 permitted, and Class 3 banned, by default

All our bikes come as standard with a 28mph motor limit making them Class 3. Adding a throttle to the standard bikes will make them illegal for public use in every state. We can configure bikes to comply with class 1, 2 or 3 though. Please send us an email for more details.

Laws vary in different states / countries. Please check your local regulations. Here is a good resource of information in the US:
