This bike impressed in testing.

There are quite a few smart electric bikes on the market. And with increasingly smart motors from Bosch, Fazua and Mahle, almost every e-bike is becoming an app-controlled software donkey. To stand out from the crowd, bike manufacturers have to come up with more than just app connectivity, adjustable support parameters and GPS. Lemmo did it and added some very practical features to its One L electric bike. But what makes the Lemmo Bike One L so special?

Electric bicycle and power bank mode

We tested the Lemmo One L with gearbox and in the electric bike version. The electric bike version sounds strange, but you can also order the Lemmo One L as a regular bike. And this is where the first smart function is hidden. The Lemmo One L can be used as a normal bicycle and as an electric bicycle.

Anyone who thinks of an ugly conversion and extension solution will be wrong. The Lemmo One L is a neat and nicely designed electric bike. The transmission is located in the rear wheel hub and the battery is stored between the top and down tubes. It is very easy to remove and still fits securely while driving. So if you want to ride with support, simply push the Smartpac into the frame. If you want to save the 3 kilos, you can simply leave it at home and uncouple the electric motor. This is easily done using a lever on the rear wheel. This means you won’t kick the electric motor and you can ride the Lemmo One L like any other aluminum bike. Without the battery, it weighs only 15 kilograms.

But the removable battery can do more than just power the Lemmo One L. You can also use it as a battery for smartphones, laptops, etc. It has enough power to power a standard laptop up to 65 watts. It has a USB-C port for this. A second port with USB-A configuration can be charged with 12 watts. And both worked perfectly in our test. With electrical support in the field and working self-sufficiently? – No problem.

This is how the Lemmo Bike One L works

The Lemmo One L is a typical urban and commuter bike. You can hit the road in great comfort, on thick wheels and with a relaxed seating position. With the Shimano chain change kit we tested, you can ride relaxed with and without electric drive and with sufficient transmission width. Of course, the Lemmo Bike One L is no mountain goat when the engine is not engaged, but the gear selection is completely sufficient for daily commutes around town or off-road. If you want to switch more often to sport mode without engine, you will have to request the change. And if you usually drive with electric propulsion, you can also use a belt drive. So there is no gear selection, but a maintenance-free, low-wear system.

Despite the comfort, you can also pedal in a sporty way. Even without a vehicle, the cross-country speed can quickly reach 25 km/h. If you have activated the electric tailwind, you will be able to do this, of course, without breaking a sweat. If you want to go further, the electric drive is a bit uncomfortable. This is noticeable when you drive at the limit and the engine cannot decide whether it should support you or not. This is one of the few criticisms of the Lemmo One L. The engineers should rework the motor control and provide an update.

There’s also little to explain when it comes to scope. Because with the Lemmo Bike One L we achieved between 80 and 120 kilometers in the test with additional laptop charging. The battery has enough capacity for daily trips to work and back home. And with the removable battery, you can charge virtually anywhere, anytime. With this, Lemmo finally destroys the fear of reach. Charging the power supply will take about 3.5 hours.

Does design follow function?

The appearance of the Lemmo Bike One L follows the function, at least when it comes to the battery. A rail takes up the down tube, leaving no room for a bag or water bottle. On the seat tube there are at least screw points for a mount. The carbon fork also offers fairly moderate bolting points. The Lemmo Bike One L is not a perfect motorhome.

What it is, however, is a true designer mobile. Because the shapes are clear, the welds are hidden and all the cables are housed in the frame. Just a little disturbs the clean exterior. This continues in the cabin. In addition to the levers for the hydraulic disc brakes and the shift levers, there are only two small, barely noticeable buttons on the handlebars that control the electronics. A speed and battery capacity indicator, as well as information about the immobilizer, is integrated into the top tube. The position forces you to look away from the road, but at least you don’t have to type or adjust anything on the screen.

Features and tricks of the Lemmo Bike One L

In addition to the good finish of the frame, the solid components stand out. Of course, Shimano Deore gears are not high-end, but this is not necessary for city and cross-country use. The tires provide plenty of cushioning and the carbon fork ensures a smooth flex at the front. As already mentioned, braking is hydraulic. The discs are non-toxic, but with proper hand strength they are superior to tire friction. Bottom line: There’s enough power here to stop quickly in any situation.

The Lemmo Bike One L is once again very smart when it comes to electronics. With GPS and Bluetooth you can locate it at any time and there is a secondary lock for greater protection. You can activate it and open it again with the two buttons on the handlebar. This makes it even more difficult for thieves to make real profits from the illegally purchased bike.

There are also handy add-ons, like a small roof rack and factory fenders. The lighting is also fully integrated and with the push of a button the headlight illuminates our partially dark, narrow but far ahead test track.

Conclusion and price-performance

The test version of the Lemmo Bike One L with chain and battery (yes, you can also order the Lemmo Bike One L as a pure bike without electric drive) costs 1,990 euros. The ST version with lower entry has the same price. However, the belt drive costs an additional 200 euros. But the whole concept convinced us. The smart solutions work very well, the removable battery is a real added value and the motor decoupling and electronic-mechanical hub locking are great options in everyday life.

This makes the Lemmo Bike One L one of the most versatile electric bikes in the smart segment that we have ever tested. Its excellent appearance, impeccable finish and elegant design make this bike a good choice for style-conscious travelers. So if you don’t ride at high speeds too often or don’t have issues with somewhat patchy engine control in this area, the Lemmo Bike One L is a good choice.

And especially when it comes to competition. Because you won’t get a smart electric bike from VanMoof or Cowboy for less than 2,000 euros. Compared to the competition, with Lemmo you save at least between 500 and 1,000 euros.
