    A new chainless digital e-bike is on the horizon that has the considerable advantage of generating electricity by pedaling.

    With its fully digital smart pedal bike, mocci from Germany has combined smart software with hardware to create a new kind of pedal-powered bike.

    Mocci’s core innovation is the use of a digital chainless drive unit.

    The drive system of this highly sophisticated tandem hybrid is based on the concept that a pedal-driven generator feeds the electric motor at the rear wheel – all operating without a chain or belt.


    A replaceable high-performance battery provides additional support.

    By eliminating mechanical power transmission and reducing the number of components, mocci has created a very safe and low maintenance system.

    Currently available for sale, the bike is simple in design: instead of transferring power from the pedals to the rear wheel via a chain or belt, as in a traditional bicycle, the pedals drive a generator, which provides power to the rear wheel motor or battery depending on the power generated by the generator.

    Advantages of digital e-bikes

    General point

    ① Ideal for freight e-bike

    ② Ideal for urban riding

    ③ Greatly reduces maintenance

    ④ Ideal for shared fleets and rentals

    Advantages of digital e-bikes

    ⑤ Smoother and smoother pedaling

    ⑥ Avoid expensive wear and tear parts

    ⑦ Lower production costs

    ⑧ More suitable for bad weather

    Simple control logic

    Converting mechanical energy into electrical energy and then electrical energy into mechanical energy may be a very common process in our daily lives.

    Many of the appliances we use at home are generated by wind, water or fire through mechanical energy, and then the electrical energy it generates is used to drive our devices into mechanical energy.

    Major car manufacturers have adopted the same technology

    Two of Nissan’s best-selling models, the Qashqai and the X-trail, are equipped with this technology: a gasoline engine drives a generator to generate electrical energy, which the electric motor converts into mechanical energy at the wheels.

    With this technology, fuel economy can be significantly improved, with Nissan announcing that it can travel 16.9km per litre of fuel in city driving and 13.5km per litre of fuel on the highway due to less frequent braking and less kinetic energy recovery.

    Advantages of chainless digital drive e-bike

    No chain and flywheel, no tooth plate, no discs.

    This is particularly convenient for the rental bike market, the freight bike market and even the daily commuting work market because maintenance is greatly reduced.

    Pedaling cadence can be more uniform and regular.

    Generators can more accurately detect large differences in leg muscle output.

    For example, if your left leg is slightly less strong, dynamic adjustments can be made to slow down the force on the left crank to achieve sensory balance.

    Pedaling will be more effective because one performs better when the muscle strength level is constant and even.

    Advantages of chainless digital drive e-bike

    Because there are no mechanical drive components, a digitally driven e-bike should be better in adverse weather conditions.

    Digitally driven e-bikes can more easily be made to perform better in frequent start/stop situations through kinetic energy recovery, such as in urban commuting and delivery use scenarios.

    They are less physically taxing, and no matter how rough the roads you ride, the load can be reduced by secondary motor conversion.

    There will be new possibilities for exterior design, such as a foldable e-bike that can be designed more easily given the absence of a chain and a simpler, more streamlined bike structure.

    Thanks to fewer driving components, the cost of producing an ebike should be reduced, and economies of scale will then start to kick in.

    Disadvantages of chainless digital drive e-bike

    The biggest disadvantage is that no matter what scenario you convert mechanical energy into electrical energy, or from electrical energy into mechanical energy, there will be losses.

    When you move the leg directly on the pedals and then transfer it to the rear wheel, there is only a small loss of energy.

    If you use mechanical energy converted to electrical energy and then transfer it to the rear wheel, the total mechanical energy received by the rear wheel is about 20% less.

    Disadvantages of chainless digital drive e-bike

    Poor performance in hill climbing

    A 250Wh battery alone can barely provide the extra energy needed for uphill riding, even on less steep climbs.

    So on a standard e-bike, the strength of the rider’s individual legs plays a decisive role in climbing.

    This technology is ready for cargo e-bikes, and may not be quite right for other e-bikes, especially the e-MTB.

    In 2013, Mando introduced the digitally driven “Footloose” e-bike, the only e-bike of similar design on the market to date, and a chainless version is now available.


    9 years later, it could only find one online dealer in London offering the “Footloose” e-bike.

    Riding tests showed that the bike could not climb on slightly steep city roads, although similar tests showed that the new and improved model in 2015 had improved climbing performance.

    However, kinetic energy recovery from frequent starts and stops on urban rides offers the potential for recharging, making digitally powered e-bikes and e-freight bikes more efficient.

    Here we have to mention Mocci, a very promising digitally driven e-bike that uses Schaeffler’s digital drive module and looks so advanced that it is already in mass production for several cargo e-bike manufacturers.

    Lack of natural riding feeling

    Many e-bike riders may complain that digitally driven e-bikes offer a different riding sensation.

    This happens every time new technology comes along.

    For example, some people don’t like electric cars because they miss the roar of the internal combustion engine, as if it were more natural and relaxing to hear engine noise than silence while driving, which is why we expect the same objections to emerge with digitally driven e-bikes, although they will gradually shrink over time.

    The lack of natural riding feeling

    Why digital drive was first and foremost adopted for the cargo e-bike

    A significant number of e-bike freight manufacturers will have digitally powered cargo bikes on the market by 2023.

    In fact, this technology does perform particularly well for freight because:

    The e-bike is very effective at bridging the last mile of logistics delivery, with frequent starts and stops to maximize the benefits of kinetic energy recovery, and the heavier the load, the more beneficial kinetic energy recovery.

    Why digital drive was first and foremost adopted for the cargo e-bike

    The e-bike usually has three or four wheels, and can generate electricity by pedaling even while waiting for traffic lights. City roads are usually flat.

    The maintenance cost of an e-bike is high, especially because the chain, flywheel and discs will be under heavy load. Without a chain, there would be far fewer maintenance items.

    So, what do you think of this innovative e-bike drive ?
