    S-pedelecs

Silent performance for
every application

The neodrives rear motor turns any e-bike into a comfortable, powerful and virtually maintenance-free mode of transport. Thanks to its position in the rear wheel, it offers a particularly natural riding experience, high agility and an exceptionally quiet drive – ideal for everyday use, commuting and challenging tours.
The neodrives Z25 is not just suitable for classic pedelecs. Its strength and robustness also come into their own in cargo bikes and S-pedelecs. Only a direct-drive hub motor enables S-pedelecs to reach a genuine 45 km/h – efficiently, confidently and reliably.

The modern design with a semi-integrated battery ensures a clean, uncluttered look. At the same time, the optimised thermal stability guarantees consistent and reliable assistance even on long or steep routes.

The Swabian e-drive supports natural pedalling precisely and harmoniously. The torque sensor is integrated into the motor and protected; the entire drive is completely maintenance-free. Thanks to rear-wheel drive, wear on the gears and chain is significantly reduced – maintenance intervals are considerably extended. Compared to mid-drive motors, a chain set wears up to six times less.

This means that both end customers and specialist retailers benefit from a high-quality, efficient and durable e-bike system of the highest technical standard.

Silent direct drive

A neodrives rear motor is an electric motor that sits directly in the wheel hub without a gearbox and drives the wheel directly. This design ensures silent performance!

Low-maintenance and durable

The Z25 is completely maintenance-free. The rear-wheel drive significantly reduces wear on the transmission components – extending service intervals considerably. Engines with over 70,000 km are not uncommon on the market.

Produced sustainably

Alber GmbH operates in accordance with ISO 14001:2015. We place great importance on short supply chains: EU, Germany and regionally from the Swabian Alb. The neodrives is designed to be very resource-efficient. Components are high-quality and durable. Furthermore, we pursue a green and sustainable service strategy.

    The new SimplyRide app offers impressive features including adjustable motor power, assist levels and the ability for end users to update the software. Furthermore, the app can be used as a ride display and to read out error codes
  • More torque
    The new Z25 motor offers up to 55 Nm of torque
  • Starting from a standstill
  • compared to the current Z20 e-bike motor, the Z25 offers the ‘start from a standstill’ function, i.e. it provides assistance or starts moving without any initial movement. This makes it particularly suitable for handbikes and similar applications
  • The newly developed thermal compound for the stator significantly improves heat dissipation: as a result, the Z25 can handle hill climbs at constant power for up to twice as long as the Z20 without reaching thermal limits.
  • The Z25 motor is fully backwards compatible with the components of the Z20 system. In addition, we offer a wide range of battery options with capacities of up to 950Wh.

Testimonials

What our customers say about us

Andi G. from Hallstadt

Staff member at Radladen Bamberg & private neodrives commuter

After riding your system for just a few minutes, it struck me what I’d actually known all along but had long since forgotten: a rear-wheel drive is the best option for a pedelec in everyday use. It simply feels closest to cycling. The virtually silent drive is a delight compared to all mid-drive systems. The gear changes on the derailleur are smooth, with no clanking or banging from the chain when accelerating. In the long run, this will also lead to less wear and tear on the components.

Patrick F. from Münster

I decided at very short notice to fit the neodrives Z20 drive to my cargo bike and have had nothing but good experiences with it. The motor is virtually silent and provides more than enough assistance, even when the bike is fully loaded. I’m already familiar with the benefits of rear-wheel drive from my everyday bike. The Z20 has also pleasantly surprised me because it uses energy recovery and recharges the battery when riding downhill.

Walter J. from Dornbirn

I went on a cycle tour from London via Berlin to St Petersburg on my Simplon Kagu fitted with your hub motor. In short, I think your drive system is perfect for tours like this and I have, and will continue to, highly recommend it to everyone. Kudos to the developers and the whole team. Please keep up the good work with your development.

Klaus M. from Mandelbachtal

After several test rides on e-bikes from a wide range of manufacturers, I was ultimately won over by the overall design of the Neodrive rear-wheel motor. My reasons for this align with your points (a powerful, dynamic and very quiet drive, with subtle use of assistance). I’ve been riding my SIMPLON-KAGU with the Neodrive rear motor for three weeks now, and I’ve already covered 400 km on it. Simply brilliant!
