Thōmas SA is celebrating their new location in Santa Monica, California in style.

On Friday, the Swiss bicycle company released their all-new Swissrider eBike in both an Urban/Gravel and Road version. Thōmus makes the claim that their new “lightweight and versatile” electric bike weighs in at only 25 pounds, claiming the Swissrider to be the “World’s lightest ebike”.

Unfortunately for Thōmus, the Cannondale SuperSix EVO Neo already checks in at a claimed 24.9lb (11.3kg) and the Scott Addict eRide at just 23.1lb (10.5kg), so the claim of the “lightest electric bike available” is likely not be true, depending on the actual weights of these bikes. Not only that, but the Ribble Endurance SL e Hero also claims to be less, at 10.5kg. To be fair, the Swissrider is still impressively light at 11.5kg, and it’s also less expensive than the $10k SuperSix Neo.

Thōmus USA is a retailer and manufacturer of “world-class” road, mountain, and gravel bikes designed by Thōmus SA of Switzerland. The bikes are fully assembled by hand at the on-site workshop. The company was founded in 2021 and operates a flagship retail boutique in Santa Monica, California.

The new development is a milestone for Thomas Binggeli, CEO, and Founder of Thōmus. “The Swissrider is an e-bike for life and is light enough to carry up the stairs and hang on the train without effort, yet with enough power to ride with ease. Only a discreetly integrated control element on the top tube suggests that this is an electric bike“, he added.

Thōmus developed the Swissrider at its headquarters in Oberried, where Binggeli started bike production on his parent’s farm thirty years ago.

At the Swissrider’s base is its “ultra-light” high-modulus carbon frame and its drive technology from Maxon, which is the same technology that is found on NASA’s Mars Rover. “We are excited to partner with Thōmus and are convinced that light-ebike drives have a lot of potential in urban life,” said Eugen Elmiger, CEO of Maxon. “The Swissrider relies on sleek design, super-light construction, and a natural tailwind from Maxon. A promising package for this market”. He added.

The Swissrider is available in three colors: Dark red, black, and sand. Thōmus says that the bike is designed for all riding needs, from a commuter or fast road bike to a gravel rig.

There are integrated front lights and a monocoque front handlebar/stem combo in either the drop bar (road version) or the flat bar (commuter/gravel version).

It would also make it a motorcycle according to most of the 50 states.

I really think those extreme sloping top tubes are ugly, bu most everything is like that these days. Also..
BikeRumor stated the Wilier Filante Hy Ebike can be had as low as 22lbs.

NEED at least 35mph

That would make it technically and legally a motorcycle and subject to DOT rules and regulations.

But yeah, sure. Online customers going 35mph assisted is a SUPER good idea. *eyeroll*

In Europe, the limit is 250 W / 25 kph (16 mph) if you want to drive it unregistered.

Ridiculous, I know. 20 mph would be perfect for longer rides, but the idea of this bike is that it doesn’t limit you from going faster. You really only need to assistance in uphills and in headwind.

No shocks? No need!

I hope it’s light. It only pumps out 30nm! That’s trash. What is this, 2005?!

What it is, is an ultralight ebike that doesn’t restrict your normal pedaling. Not the regular one where you need all that assistance.

There are those too, if you’d rather buy them.

You mentioned Shimano..I have a ebike and need a new Shimano battery. I have been told they will only be available in October,2023. That leaves me all summer with an ebike but no battery. I am not impressed with Shimano and there service. I am 76 and really enjoy cycling.
.I have been looking at Pedego ebikes which do not use Shimano battery.
