The DM01

An Introduction

A few short years ago, a team of engineers banded together to design a new line of high performance middrive motors designed specifically for the conversion market, targeting the wide array of bike, trike and recumbent designs that are available today. Introduced to the USA market in late 2023, the DM01 and its smaller iteration, the DM02 have become strong players in the conversion market.

The DM01 is available in two power ratings - the 750W used for bikepath legal purposes (North American), and the off-road focused 1000W with tractor pulling torque. The 750W motor has a torque rating of 120nm and can handle up to 26A of power. The 1000W unit offers 160nm of torque and 30A of power handling. Both motors are user adjustable for 48V through 60V nominal battery packs. Keep in mind that these ratings are what are considered "nominal". They are each capable of handling what is termed "peak ratings" when the motor needs to supply extra bursts of power during acceleration, heavy loads or hills. Peak ratings are designed to be used only for short periods, while nominal usage is considered times when the motor is used under ordinary uses.

Each DM Middrive has multiple sensor inputs designed for smooth power flow and user convenience and comfort. The DM01 boasts full cadence and torque sensing to create a smooth power flow. Cadence sensing is what comes on most production level hub motor e-bikes. It is basically an on/off system. Start pedaling and the system senses this, and based on the level on the display, the controller sends power to the motor. A torque sensor takes that premise many steps forward. It not only senses that you are pedaling, but it also senses how hard you are pushing down on the pedals. Need to accelerate hard? Just push down hard on the pedals. Hill? The system senses this and sends appropriate levels of power to the rear wheel.

How about a throttle? Don't feel like pedaling, or have a sore knee and just want to get home? The DM01's come with a throttle to do just that. Try that with a Bosch or Yamaha middrive.

How about shifting, isn't that hard on the gears? Not with the DM01. The kit includes a shift sensor that senses movement in the deraileur cable and momentarily cuts power while the shift happens. Power is then smoothly reestablished after the shift is completed. This is standard equipment on every DM01.

The DM Series of middrives have been designed from the ground up to be able to handle a wide variety of conditions. With an IP65 water resistance rating on all components, the entire drive system can continue to be used regardless of the conditions or weather. Aluminum alloys are used throughout the motor construction for weight control and heat dissipation.

One of the unique features of the DM01 is its advanced programming capability, all built into the T24 Display Interface. Log into the display and you will be presented with main settings, like wheel size and battery voltage. Advanced settings include the ability to fine tune how the motor and controller interact with your style of riding and conditions. All of this is done within the convenient display interface and is locked behind two levels of password restrictions.

Compatibility was designed into the DM01 with bottom bracket widths of 68mm through 110mm. These motors can fit around 95% of the available frame styles on the market including bikes, trikes and recumbents. A wide range of chainring sizes and offsets are available to accommodate different conditions. Hills, loads, proper cadence, desired speeds, and proper chainline all come to mind when adjusting the teeth of offset on a chainring.

At 11 lb 13 oz (750W) and 12 lb 15 oz (1000W) these motors offer a lot of power in a relatively light package. For lighter weight solutions, consider the DM02, weighing in at just 8lb 6oz. The motors are designed to operate at a quiet 50db rating. The systems are designed to handle temps from -4 degrees Fahrenheit to 122 degrees Fahrenheit.

The interior design of the motor includes advanced heat sinking to control heat buildup during use, along with a 40.27 to 1 reduction gear ratio for increased efficiency. Double clutches allows effortless pedaling during those rare times when the motor may be off.
