Meet Erik Buell’s FUELL Flow and Fluid EVs

The innovator who shook up the motorcycle world takes e-bikes and e-motorcycles to the next level.

It wasn’t so long ago that engineer, designer, innovator and mover and shaker Erik Buell rolled out his own line of high-performance motorcycles bearing his name.

Today, more than 130,000 motorcycles credited to his name. Later, he upped the ante with his line of road-race-ready bespoke bikes under the Erik Buell Racing or EBR marque.

No pipes, final drive, foot brake, clutch—Erik Buell’s latest motorcycle creation, the Fuell Flow, is powered by electrons and innovation.

“Erik Buell is considered to be a pioneer in motorcycle technology and earned his induction into the American Motorcyclist’s Association Hall of Fame in 2002,” says Mary Baboyan, Public Relations Manager for Buell’s new EV-forward company FUELL.

“He has 40 years of engineering experience, and founded his own motorcycle racing company Buell Motorcycle company which eventually merged with Harley Davidson. His knowledge on two wheelers have transferred over to his new passion project, the tech packed, spec’ed out FUELL Fluid E-Bike.”

FUELL, by the way stands for Freedom, Urban, Electric, Love, Life as well as providing a subtle link to Buell.

Now Buell has turned his talents and imagination loose on the rapidly expanding universe of e-bikes and e-motorcycles. Together with a team of remarkable people, the results are something quite remarkable.

The Fluid, e-bicycle will be going into production for delivery to begin as early as August or September of this year. The bike re-thinks the basics of bicycle design and may well be a product that leads to resets of the norms for e-bikes.

The Fluid features a mid-drive Bofeili 500W pedal assisted motor, giving it 100Nm of torque, that is designed to deliver strong acceleration. The bike is built with a custom aluminum alloy frame for both durability and light weight.

The Flow e-motorcycle is slated to begin hitting the streets late in 2020. Two versions are offered right out of the gate; the 11kw model with an MSRP of $10,995 (USD) and the 35kw model with an MSRP of $11,995.

Those prices compare very favorably, for example, with Harley-Davidson’s LiveWire that has an MSRP at $29,799. Pre-orders can be placed for either model now.

Pre-order deposits of $500 are refundable until the customer’s Flow enters production. As the Flow nears production, a member of the Fuell team will reach out to discuss the FUELL Flow Purchase. Once the customer has decided exactly which model, color, features, services, and accessories they want, final confirmation will occur 1 month before the beginning of production.

The exact delivery date of each Flow will be communicated to the buyer as the transaction is finalized. Each Flow will be delivered directly to the buyer, where an introduction to the Flow is provided. Detailed warranty, maintenance, insurance and refund policies will be communicated in advance of production. Further, information regarding the use of the Flow and the dedicated rider hotline will also be provided.

First, some details on the Flow.

FUELL Flow Motorcycle Overview

Visually, the immediate impression is the electric bike’s elegant design with smooth, flowing (appropriately enough) lines. It is touted to have an urban ride range up to 150 miles, fast charge under 30 minutes, and the acceleration of a superbike with a curb weight of only 400 lbs. The absence of any final drive components and transmission saves a lot of weight and eliminates a lot of wear-and-tear prone components that are still present on other designs.

The Flow smooth and slippery in design, light in weight and pre-orders are being taken now.

The Flow has numerous innovations like the exclusive patent-pending rear wheel motor, the connected dashboard, and 50 liters of storage in its monocoque magnesium chassis. Using a modular approach, the Flow is designed to easily evolve with technological progress. The modular design allows for easy upgrade of the battery, the wheel motor, and the charging system. For those of us who don’t relish the push and pull of manually maneuvering our bikes, the Flow includes forward and reverse walk assist.

The battery pack as well as the rear wheel motor or the fast charging socket can be upgraded to the owner’s preferences. The connected dashboard receives regular updates and evolutions. The system is designed to assure access to the latest technology.

In addition, the Flow integrates the latest safety technologies that include blind side detection and front and rear collision warning systems and a rear-view camera. The Flow includes ABS brakes with integrated regeneration at the rear brake.

One of the striking innovations that goes along with the rear wheel motor lies in the intelligent ABS braking system’s linkage that use the rear wheel motor for progressive braking instead of having a separate rear brake.

The FUELL Flow sets a new standard for stand-off operating convenience; the FUELL app allows you to find, unlock, and start Flow. The app is used to open the secured storage, access the charging port, flip up the seat, open the owner’s manual, or check the battery level. You will receive notifications and maintenance alerts on the app, use GPS, and contact or stay in touch with FUELL. Check out the FUELL website at: https://fuell.us/us/
