Production-ready Twike 4XP Human Powered Hybrid Shows Up At Frankfurt 2013

Human Powered Hybrid

The 2013 Frankfurt auto show has officially wrapped up, but there was a tiny human-powered hybrid Twike booth nestled away in a quiet corner of the massive show that we haven’t yet covered. The Twike 4XP, originally unveiled at the Progressive Automotive X-Prize competition, was on display along with a few production Twikes, with news that a consumer version of the 45 mph EV was coming later this year. You can find out more about the Twike in this article, below, which originally appeared on CleanTechnica sister site Gas 2.

Frankfurt 2013: Twike Trots Out the 4XP Human Powered Hybrid


Nestled away in a small corner of this year’s Frankfurt auto show, the tiny Twike company rolled out its nearly production-ready, X-Prize contending Twike 4XP plug-in hybrid. The sci-fi inspired, jet-fighter cockpit-styled Twike isn’t what you might think it is, though. It’s a hybrid, in that it combines the power of its electric motor with a more conventional power plant — in this case: a human power plant.

That’s right! The Twike is, essentially, a pedal-assist covered bicycle that’s intended primarily as low-impact, zero-emission urban transport. If the batteries go low, you can pedal them up. If you’re going downhill, you can use a form of regenerative braking to charge the batteries. If it’s raining, you won’t get wet. The best part, to me, is that you can use the electric motor more on the way to work and avoid showing up sweaty and stinky, and then pedal more on the way home as part of your cardio/workout routine.

The other best thing about the Twike 4XP, though, is that it really can replace a small car — especially with the upgraded battery packs and electric motor with a 45 mph top speed and decent, 50+ mile range as a pure EV at 35-ish mph — which was good enough for a trip around the world, two years ago.

SO, while the Twike might not be perfect for everyone, of course, but if you’re in the market for a small, 2-seat commuter with a proven track record of sales (Twikes have been around, in Europe, for almost a decade), manufacturing know-how (again: decade), and safety (the Twikes have been crash-tested and reportedly meet stringent TÜV standards), the Twike 4XP might be just thing.

Here’s hoping some enterprising American company has the sense to bring one of these over to the ‘States as an NEV, then. We’ll keep you posted. In the meantime, you can check out some of the 4XP’s design drawings, and get a sense of what it will look like in different color combinations, over at the original article. Enjoy!

    Why not tadpole configuration?

  • agelbert

    I like it!

  • It’s not 20k, that’s the price sans battery, the basic model with smallest battery and battery controller (to ensure proper charging) is 23,500 Euros or so, or heading towards US$32k, just way over the top.

    I guess the low top speed is to make it more inline to compete with a moped. Looking at the link that Nick provided, I have to agree. This should be more of a 3k to 5k cost, not 20k.

  • Nick

    Did you look at the price joe? This is a joke. Who would spend that on this toy?

  • cowboyleland

    Sure would be great if the Twike people could talk to the eVe people. That is the hybrid I’ve been waiting for.
