The range of BMZ engines is interesting on the one hand for its versatility, and on the other for its model claiming an impressive torque of 112 Nm.
On an electric bike, the motor is one of the key parts without which nothing would happen. It is also one of the most expensive components, alongside the battery. The information site eBike News is precisely the relay of an interesting range of engines, and whose torque of the most powerful model necessarily challenges.
Mainly known for its batteries, the manufacturer BMZ has also positioned itself in the engine systems niche. Its “BMZ RS” is thus one of the most powerful on the market… in terms of torque. As a reminder, the torque acts on the starts, the times and the ability of the bike to climb a strong positive drop, for example.
More than 100 Nm of torque
The higher the torque, the more dynamic the bike will be. In town, for example, a torque of 60 Nm is generally sufficient to meet the main needs. Except that here, the “BMZ RS” reaches an impressive torque of 112 Nm, for a total weight of 3.6 kg. Who is it for? Quite simply, electric mountain bikes.
Having to survey rough and extreme terrain, eMTBs are often equipped with the most high-end components on the market… at such expensive prices. But BMZ is not content to address this more niche practice, since its “BMZ GT” engine is available in several versions, let’s say more urban.
Versatility
The “BMZ GT” is indeed designed according to three different torque levels: 55, 75 or 85 Nm. This system weighs the same as its big brother and benefits from the same IP56 certification. The first number means that it is dustproof, while the second number guarantees protection against water jets.
The fact is that these torque thresholds make the GT engine suitable for city electric bikes, but also hybrid bikes that need a little more dynamism on beaten paths or other small, slightly furrowed paths. It should be noted that BMZ motors comply with the European laws in force: they propel a bicycle up to a maximum of 25 km/h.
