RGNTs first electric
motorcycle ready
for mass production.

A mobile Stromer silences the street.

At first glance, the Regent No. 1 appears as a classic retro-styled bike. When looking close enough you can see a display, where originally circular instruments are. And after the first ride, it becomes clear that Regent No. 1 has a quiet electric motor instead of a rough single cylinder. The motorcycle manufacturer RGNT has created an electric bike in the 50s look with the mission to silence the streets.

Industrialization of the motorcycle battery

The Swedish company Regent Motorcycles was founded in December 20218 by Jonathan Aström with the vision to design classic motorbikes with an environmentally-friendly powertrain. RGNT presented its prototype in May 2019. The company is already one step ahead in the motorcycle industry, not even the big players in the market offer electric motorbikes. One year later after the prototype was produced, the e-vehicle producer reached out to e battery systems, to get the model ready for mass production. The design was already clear at the beginning: A retro-styled bike was the aim. This is why the focus is pointed directly at the heart of the motorbike: power unit and storage. For e battery systems is clear to get the electric motorcycle ready for mass production the costs of manufacturing have to be reduced.

Manufacturing of the lithium motorcycle battery

  • Selection of new material
  • Redesign with the aim of series production
  • Process optimization
  • Searching supplier for subassembly
  • Assuring security and proximity of supply by making long-term contracts with cell manufacturers and supplier of electronics
  • Automation of manufacturing

From prototype to market-ready electric motorcycle

First step before the motorcycle battery can be manufactured is the analysis of the market potential. Step by step the safety is improved and all criteria such as production-optimized component selection, weight and energy content are taken into account.

 

The lithium motorcycle battery with 60 Ah enables a range of up to 150 km / h and a silicon carbide switch technology increases the efficiency of the powertrain for more range and drive power. The engine is located in the heart of the machine, but in Regents No. 1, there is an oversized drum brake in the rear wheel. Practical advantage: energy is regained through recuperation on the rear wheel.

 

The battery of the electric motorcycle of the Swedish start-up RGNT consists of several complex components, such as the cell, the BMS (Battery Management System), and the BPU (battery protection device). The marketability of the electric motorcycle requires high reliability in terms of delivery, which is why critical components are manufactured directly at e battery systems or secured through long-term contracts with the suppliers.

 

“The simply called No.1 machine is a visual treat and is based on the design of classic motorcycles such as the Yamaha SR 500.” - ADAC

Christoph Pürmair, project manager of e battery systems, explains:

 

“To get the battery of the motorcycle ready for mass production we focused on the redesign especially on using standard components in terms of cost-efficiency. What was also very important was that the construction of the battery is simple and with little effort. Many steps could be automated to remain competitive in the long run."
