New drive system with torque sensor

Diamant 365: slim, lightweight and affordable e-bikes with a new drive system

In recent years, the range of lightweight and slim e-bikes has virtually exploded, which means that those interested now have a pleasingly large selection of different models. However, they differ much less when it comes to the electric drive: This comes to a large extent from Mahle with the well-known X35 system. In this respect, it is definitely a welcome change when a large manufacturer relies on a new system!

So Diamant brings with the new 365 series a new drive system that was developed “specifically together with Diamant and Trek” by Hyena. Incidentally, the producer from Taiwan is not completely unknown to us, after all, we had already tested a drive of this manufacturer in the Delta S from Mokumono.

Here as there, the integrated torque sensor (in the bottom bracket) is particularly worth mentioning: the measurement of the pedaling force achieved with it allows the motor power to be perfectly adjusted, which leads to a particularly natural riding feel. A feature that the competition with Mahles X35 drive can’t offer, by the way.

The other components of the electric drives of both suppliers are more similar: The G2 hub motor in the rear wheel offers a torque of 40 Nm, the battery is also fixed installed in the down tube and has a capacity of 250 Wh. A range extender is offered as an option, which offers an additional 250 Wh and is supposed to double the range from 60 km to up to 120 km (according to the manufacturer). Typical for this category of bikes is the lack of conspicuous controls: the Diamant 365 only has an easily accessible and compact button on the left side of the handlebars, which can be used to control the drive and display the battery capacity. A free app can also display further information about the ride on the smartphone.

All this technology is packed into an aluminum frame, which is designed with a slightly curved top tube. And for a more comfortable ascent and descent, the 365 is also available with a comfort frame in trapezoid shape. In both variants, the cables and wires are neatly routed through the inside of the frame starting at the stem, resulting in a clean look.

In addition to the regular Diamant 365, there is also the 365 Deluxe. Both model variants are equipped with mudguards, side stand and a lighting system from Herrmans, as tires are 40 mm and the braking system comes from Shimano’s MT200 series. Differences are found primarily in the circuit: the 365 is equipped with a Shimano Altus derailleur with 9 gears and a 11-36 cassette. The 365 Deluxe, on the other hand, has a 10-speed derailleur from the better Shimano Deore series, and the cassette is also a bit more suitable for climbs with 11-46 teeth. Also, a luggage rack is mounted on the Deluxe model.

Measured against the current situation on the market, the prices of the new Diamant 365 e-bikes are quite fair: the Diamant 365, which weighs 17.5 kg, is offered for 2,449 euros, while the Diamant 365 Deluxe, which still weighs a light 18.4 kg, costs 200 euros more, bringing the final price to 2,649 euros. Interested parties can choose from three frame sizes in each case. The color of the Deluxe bikes is always oxide green metallic, while the regular 365 is deep black and the 365 with comfort frame is also available in aventurine red metallic.

All further information on the new 365 series can be found directly on the Diamant website.
