If you have been following the progress of electric vehicles over the last 5 –10 years you know we are in an exciting time. There are more electric vehicles available to purchase now than there have ever been. Public charging infrastructure is growing as well, though not rapidly.
The most news is usually about EVs with four wheels. CleanTechnica has dedicated extensive coverage to Tesla’s EVs and many others. The electric vehicle revolution doesn’t stop with cars, SUVs, and trucks — it includes e-bikes, motorcycles, and trikes.
At the moment, everyone can’t afford a new electric 4-wheel vehicle, so the 2-wheel EVs may provide an opportunity to own and operate electrified personal transportation for the first time. The lower price point is just one appealing aspect of e-bikes. Andrew Davidge, founder and lead designer of San Francisco, CA-based Vintage Electric, answered some questions about its new line of 72-volt e-bikes.
How many bike models are there in the 2022 72-Volt Performance Line?
Three: the Roadster, Scrambler, and Shelby.

Does each bike’s purchase price include a home charger?
Yes.
Can the e-bikes be charged with public chargers?
No.
Does each one come with a warranty, if so, what does it cover and how long does it last?
Yes, two years that covers everything.
What is the lifespan for each model’s battery?
1000 charge cycles. Most customers get between 3 – 5 years before wanting to upgrade.
What kind of brakes do they have?
Hydraulic disc brakes with built in regenerative braking.
Are they suspended, and if so, what kind of suspension?
Front suspension stock with optional suspension seat post.

Why 72 volts, what is advantageous about that figure or amount?
We chose to increase our voltage to 72 volts for a few reasons. The most important feature is the ability to create torque. We went back to the drawing board to re-engineer our motors to create 3x the torque. The 72-volt battery allows us to keep the same (40 mph) top speed we are known for while maintaining the full torque potential of our new motor system.
We are also able to run 1000 more watts through our drivetrain without creating any more heat. Increasing efficiency and range even with our higher output.
The third great benefit is charge time. We have brought our full battery charge time down from 4.6 hours to 3 hours.

Former Tesla Battery Expert Leading Lyten Into New Lithium-Sulfur Battery Era — Podcast:
I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
