Santa Monica Electric Vehicles at Test IT Track in Taipei

From 20 to 23 March 2013, Santa Monica Electric Vehicles focuses on its BEAMts torque sensor at the ExtraEnergy Test IT Track in Nangang Exhibition Hall, Cargo Ramp, 4F at Taipei International Cycle Show.
 

 
At the Test IT Track in Taipei, Santa Monica Electric Vehicles will present electric bikes with the company`s BEAMts torque sensor.

BEAMts Torque Sensor
Unlike other torque sensors that measure force at the bottom bracket or at the rear axle, BEAMts measures force on the chain and converts that force into standard 1-4 volt throttle output that requires no further processing at the controller.

>> Introduction (YouTube)

Santa Monica Electric Vehicles uses a semi-rigid beam that flexes when pressure is applied by the bike’s chain or belt.

A hall sensor measures that deflection and an onboard processor takes the raw sensor feed and outputs a smooth, conditioned signal that replicates a standard 1 to 4 volt throttle.

The company pots the entire unit so that it’s completely weatherproof.

>> Durability (YouTube)

Because the housing is one continuous piece of aluminum, it expands and contracts at a constant rate so it’s not affected by cold or heat.  "Some competitors use a mix of steel and aluminum which have different expansion rates leading to binding issues during temperature extremes", states the company.

The unit self calibrates at start up and 3 times a second thereafter.  It works with either a pulley or sprocket.  It isn’t affected by rough use or tire changes and requires no special set up at the factory.

>> AutoCalibration (You Tube)

BEAMts works with a front, rear or center mounted motor.  It works with an internal hub or rear cluster and also with a multi-speed crank.

A complete programming package is included which will run on almost any PC and let you set up your desired preferences. Once those settings are determined, you order pre-programmed units that simply plug into your controller.

The software let’s you adjust the ramp down which determines how fast power cuts off after you stop pedaling.

You can also adjust the ramp up which controls how quickly power ramps up when torque is applied to the pedals.

In order to facilitate quick evaluation of the BEAMts by clients, the company provides generic plates which mount in the existing bottom bracket.  Usually, the company can set up a sample on bikes in under two hours.

Santa Monica Electric Vehicles offers a split system which lets you plug a throttle directly into the BEAMts as well as a programming package to control both inputs.

The company can customize the BEAMts shape and orientation as well as the color to match a client’s individual needs.

The company has completed lab testing with SGS labs in Taiwan and contract manufacturing agreement with Fairly Wettsen.
