Delta’s New Innovation Takes Battery-Motor-HMI Integration to the Next Level
Over the last few years, Delta Electronics Inc. has been focused on developing a compact, lightweight and powerful mid-drive motor. Now, the company is set to launch an integrated suite of products with an innovative Human Machine Interface at the core of the new system.
Delta’s R&D center is located in Taoyuan’s high-end industrial heartland. That’s where The Show Daily sat down with Josh Chi, Delta’s Director of E-bike Solution Division, for a wide-ranging discussion covering Delta’s entry into the e-bike space, as well as the finer points of the new Total Solution system.
Delta entered the e-bike market in 2021 when Taiwan’s Ministry of Economic Affairs selected the company to develop locally made e-bike motors.
“Although we were well-known in the electronics industry, when we first entered the bicycle industry, we were nobody,” said Chi. “There was a clear gap between us and the rest of the industry, with the resources and intelligence provided being very limited. Therefore, our initial focus was on how to approach all areas of the bicycle industry with humility and build trust over time,” he said. Delta’s success in building industry partnerships has been key to their new Total Solution product offering, which can be seen on a display eMTB at the Delta booth.
The Delta Mid-Drive Motor has been in development for several years and earned a Parts and Components Award at the 2024 Taipei Cycle d&i awards, and has just received a 2025 IF Design Award.
The motor is extremely compact yet powerful. “Our customers think that in the future the e-bike will need to look like a normal bike. This is the target. But right now, the e-bike downtube is huge and not a very good look. So, the motor is a very key part on the whole bike,” said Chi. “Delta Mid-Drive packs 100Nm into a small, circular-shaped package. The price is also very competitive. We, however, can supply a more powerful and very compact motor at an attractive price.”
Aimed at mountain, trekking and cargo bikes, the 111mm x 92mm 36V motor weighs 2.9kg, and has a peak assist torque of 100Nm. Rated power is 250W with peak power of 750W, a maximum speed of 28mph and maximum cadence of 120rpm.
The complexities of the motor, along with the other components that make up the Total Solution, meant working with partners to fine tune component customization, since the off-the-shelf models didn’t quite fit the mid-drive specifications.
The battery, for example, has been developed in partnership with a Taiwanese battery maker. The 600Wh 36V 16Ah slim tube design weighs 3.5kg, and is the first Delta-branded battery to go into the market. “We are also currently working on another battery product with a local battery company that will be launched at either Eurobike or at Taichung Bike Week,” said Chi.
In developing the HMI, Delta partnered with an e-bike HMI manufacturer to develop two Bluetooth-enabled versions: the RC10, suitable for suspension mountain bikes and the RC9/CD8 combination for trekking or cargo bikes. The RC10 (78 x 46 x 54mm) is a standalone handlebar-mounted control with a high-brightness LCD (1,000–1,600 cd/m²). The RC9 (53 x 46 x 54mm) is another alternative that pairs with the CD8 display (46 x 19 x 62mm), which provides enhanced visibility with the same high-brightness LCD.
As a global electronics brand, Delta serves customers through its sales offices, R&D centers and manufacturing facilities spread across five continents.
A vitally important part of the Total Solution is the ability to provide after sales support. “After service is equally important as the product,” said Chi. “To really be a total solution, there is the need for operational data to be collected during a ride and stored in the HMI. Malfunctions can be stored as error codes in the HMI display.”
Mass production of the Total Solution system is set to commence in Q3.
“The interesting thing about this industry is that everything looks simple, but in fact the details are hidden in it. Therefore, we believe that there are no easy parts, but that each project needs to be treated with sensitivity and continuous optimization,” said Chi.
