E-Torque

$1,600.00

E Torque is the rare ebike with Torgue sensing motor stlye ready to give you the power only when needed vs just trying to max out like most speed sensor style motors. A torque sensor needs to measure the force that the rider is applying to the pedals. Typically these take the form of an entire replacement bottom bracket which has internal force sensing built into it. But other systems measure the force on the chain, the rear dropout, the rear axle, cogs, or pedals.

What is Pedal Assist? 

Pedal Assist automatically turns on the motor when you pedal. With pedal assist you do not need to use a throttle to control the motor. 

There are two types of Pedal Assist: Cadence Sensor Type which measures IF you are pedaling and a Torque SensorType which measures HOW HARD you are pedaling.

Our CrossCurrent S, RipCurrent S, and OceanCurrent have both types sensors included with every bike.  

 

1. Cadence Sensors (Basic)

The basic cadence sensor uses a magnet on the crank, it turns the motor ON when you start pedaling and turns it OFF when you stop pedaling. It works more or less like a switch.

You have to control the boost level and speed by adjusting the assist mode manually up and down. Most basic e-bikes have this.

The advantage is that it's an inexpensive way to get some sort of pedal assist onto the bike, but the disadvantage is that the pedal assistance can feel jerky, laggy and counterintuitive. Also if you want to pedal faster than the motor is spinning, the motor will actively work against your efforts.  

2. Torque Sensors (Advanced)

The torque sensor is a totally different technology that uses a  precision strain gauge. It measures your actual force on the pedal, sampling at 1,000 times per second over the entire pedal stroke. 

The harder you pedal, the more power it gives to the motor. If you pedal lighter, less power goes to the motor. It makes this adjustment in real time so it is technically amplifying your every input. It feels like you are bionic. 

Most all higher-end e-bikes use torque sensors and in some countries, cadence-only sensors are not allowed to be sold. The disadvantage is the cost is significantly higher to implement this technology as the precision component is relatively more expensive. 

 

Many people will assume that a torque sensor is ideal and represents the gold standard for PAS control, and that the basic PAS sensors represent a poor but inexpensive alternative. We don't think it's that simple, as people who prefer to regulate motor power independently from their pedal effort will be better served with a basic PAS setup.
