E-BIKE MOTOREN TEST

Which journey system is the best weil das E-road bikers? die big differences an terms des power, torque, battery capacity, noise, usability and riding characteristics nur that manufacturers schutz many different interpretations of what makes the perfect E-road bike. Nonetheless, over there are still some unifying trends. Us tested ns five most crucial E-road bike motors on die market and found out which one ist right weil das you.

Watt’s it all about? ns most important motiv specs explained

E-road bike electric motors are marketed v a last of specs and data that promise zu describe their performance. If riding characteristics and handling can’t really be interpreted from these values, lock do administer a rough and ready way zu compare motors versus one another. We’ve already taken a look weist what those specs mean und what sie should look out for an our E-road bike fundamentals article, so we won’t describe them further here. However, we’ve given you in overview of the key charme for die motors we tested bei the table below.

What makes a an excellent E-road bike motor?

Construction and weight

The best motor is only as good as the bike it ist fitted to. That said, die size of the motor can so have a huge influence on die riding characteristics. Compact electric motors provide much more flexibility weil das designers in terms von frame design. Additionally, the not nur the weight des the motor and battery, but deshalb where they space positioned that has actually a huge influence on exactly how a bike handles. If die centre des gravity zu sein as low und central together possible, then the bike möchte ride much more naturally. If die weight von the system results in a centre des gravity that zu sein shifted auch far forwards or too high, then it impinges remarkable on die handling des the bike und it tun können feel like you schutz to fight ns additional weight of the system.

Displays and remotes

Both displays and remotes space available an a whole spectrum of options from minimalistic, fully-integrated solutions to large control centres filled with features und apps. For all the system here, cycle manufacturers must use die cockpit options offered by each motiv supplier. Shimano und Specialized administer the option to fully forgo a bar-mounted far as lang as your Bluetooth connected smartphone ist provided in its stead. Together a customer, you so have the auswahl to customise die cockpit zu your angestellter preference with plug-and-play components. Despite die large variety des displays top top offer, E-road bikers wollen face the same belästigt again and again. Die remote ist often notfall easy kommen sie reach, or so clunky the it ruins ns lines von the cycle it is on. You’ll also often find ns display mounted punkt points where freundin would usually put your bike computer – it appears a fight weil das the finest handlebar ja wirklich estate is inevitable. We often discover that ns readability of displays kann sein be affected bei strong sunlight. Sadly, finish integration of the system into the GPS display sie already have on your bike ist currently nur a pipedream. However, Specialized’s system kann sein already transmit power, cadence and speed säule to a number des devices. The Turbo connect display deshalb offers a good summary of your speak data, but can’t currently be used zum navigation. Us would favor to seen a display screen that combines these different elements, from die functions of your general practitioners (i.e. Navigation) to ns display of key riding charme from die motor. There’s ausblüten huge room for improvement here.

It’s not all about die battery: range

Obviously, a large battery v lots of capacity can provide an ext juice and provides far better range. You’ll uncover battery capacities range from 250 Wh zum FAZUA and Ebikemotion, 504 Wh weil das Shimano to bolzen 300–625 Wh zum Bosch models. In addition, manufacturers favor Ebikemotion or specialized offer additional range-extender batteries which tun können be mounted bei your bottle cage and increase your variety with up to 250 Wh capacity. However, it’s important to grad that selection doesn’t just depend on the size of your “tank”! Consumption, efficiency und power of the motor, in addition to around 20 various other variables – amongst these, driver weight and time spent above die 25 km/h assistance limit – space all deciding factors in how far you can go. That’s why it’s nearly impossible to make a basic statement about range. You can find a an ext detailed discussion about this in our feature “The truth about lab tests”.

Which system: hub or mid motor?

In contrast to ns eMTB sector, die E-road bike market is blieb fresh-faced und finding that is feet. That so means the there is a varied range des systems available. Bosch, Shimano and Specialized choose zu use mid motiv drives which create a centrally positioned centre des gravity and integrate ns bottom clip into the motor. FAZUA usage their own bottom bracket/gearbox plan integrated into die frame, that is driven by a removable battery and motor unit. This system allows FAZUA bikes to quickly shed the 3 kg weight of the motor and battery und be converted kommen sie what ist effectively a normal, unpowered road bike.

The MAHLE Ebikemotion system uses a hub motor. This means a traditional bottom bracket kann be used, with the battery equipment inside ns down tube und the motiv inside die hub of the rear wheel. This configuration enables bike manufacturers to entwurf frames v a slim silhouette similar kommen sie a normal road bike. Extr advantages include die standard bottom bracket i beg your pardon allows for normal Q-factors und the light weight von the system which enables Ebikemotion-equipped bikes to weigh comfortable under 12 kg. However, the battery is permanently solved inside the closed under tube und has zu stay an the bike kommen sie be charged – as such, you’ll need energie sockets near zu where sie store your bike. In our prüfen we discovered a couple of other jene that freundin should consider prior to buying your bike. Die speed von a hub motor zu sein dependent ~ above how in der nähe des your wheels are turning. Unfortunately, that means that top top steep slopes, whereby your wheels are turning slowly but sie generally need die most support from ns motor, that produces die least power! it is because punkt low speeds, ns hub motiv isn’t operating in its most efficient rpm range, resulting in increased stärke draw, boosted heat, und decreasing assistance.

Mid motors are typically muscle men des the competition. The higher torque and larger batteries could indicate clear superiority on record but space inevitably associated with a higher pistole weight. In practice, mid motors deshalb have their own quirks. The Specialized system requires die battery zu stay in the frame zu be charged, despite it can usually be removed for Shimano and Bosch systems. Weil das the last two, that relies on how die bike manufacturer has chose to rechts the battery as not every model has necessarily been designed with battery removal bei mind. Die FAZUA battery zu sein charged either von putting ns drive unit into die charging position i.e. Für hilfe open, or fully removing the from die frame. Additionally, mid electric motors unavoidably transmit an ext noise due to their integrated position on ns bike with die frame effectively acting as a resonator. That means that a rider will perceive a hub motiv as quieter (even if it in reality produces an ext noise) since it zu sein further away from your ears and is quickly drowned the end while riding. However, die position des a mid motor is advantageous due to the fact that even with the increased weight, die centre of gravity tun können be made to be central and low. Every that kommen sie say that a mid motiv isn’t categorically better or worse, but bei the ende relies heavily on how ns bike manufacturer implements their particular solution. The brings us kommen sie our final point. Mid motiv systems need space for batteries the are fairly large. Manufacturers such together FAZUA and Bosch through its InTube batteries offer integrated solutions, but that tun können require far-reaching modification des the tubesets zu make die batteries accessible. Ns typical offen tube entwurf means a reduction in torsional stiffness and bei turn way that tubes oase to it is in beefed up kommen sie achieve ns same strength. Tolerances and clearances are so an necessary consideration: the Fazua system, which needs a down tube that opens over almost its whole length, depends on measurements accurate to just a few millimetres to fit correctly.

Specialized and Ebikemotion both integrate ns battery into a closed down tube. That can mean that ns battery tun können only be removed von professional mechanics, but in turn, the strength und structural integrity von the frame is improved. Zu ensure good handling und performance, manufacturers continue zu work on the challenges lock face bei terms des battery integration. When this ist undoubtedly a an essential consideration, our test aims to consider only the motiv performance des the system we have looked at.

The test: what did we look at?

During ours search zum the E-road bike motiv with die best as whole performance, us made use of the cumulative E-wisdom des our colleagues at E-MOUNTAINBIKE Magazine. Having persuaded our hairy-legged hill bikers kommen sie squeeze into bib shorts, we gott to ns task in Baiersbronn in the schwarz Forest. Us didn’t just look hinweisen how much assistance ns motors provide, however how every performs weist different cadences and speeds und where they create peak power. After all, die cadence doesn’t nur influence ns maximum power des the motor but so the efficiency des the system. Ideally, the maximum efficiency von both motor und rider must fall in the exact same range weil das a pleasurable talk experience. Die behaviour of the systems above die 25 km/h assistance limit, particularly zum a road bike, was also of concern. How smooth is the transition bolzen support und no support? ist the adjust imperceptible or obvious? Similarly, the noise produced von the different systems zu sein just as important as your integration and ease of use. We’re looking for holistic services that offer a complete and well assumed out design. We also paid close attention zu how natural the motors feel kommen sie ride. How wide ist the Q-factor? What are the riding characteristics des the system? just how does the compare to a “normal” road bike? tonnage but notfall least, die ease of charging and overall ease of use und features such as connectivity, apps, display und remote choices were scrutinised. We want to seen a complete und adaptable ecosystem that offers lots des features to ns end-user.

So what’s die best E-road cycle motor?

The truth is, that the market for E-road bikes is in its infancy und is blieb defining itself. Ns big differences in terms of power, torque, battery capacity, noise, usability and riding features seen in the systems tested right here make it clear that various manufacturers schutz different ideas von what an E-road bike must be. How great or bad in E-road bicycle drive is will count strongly top top what kind of E-road bike freundin are looking for, and also how successfully die manufacturer has incorporated the system into their in its entirety concept. Die good news zu sein that the market currently offers several great E-road bike options that we kann sein happily recommend. However, the fact that the sector is still finding that feet means that the perfect system doesn’t however exist. Many motors experiment here oase already to be available for some time but an terms of E-road bicycle use and integration are only an their erste generation. While assorted systems schutz been adopted form the eMTB sector, basically none are designed specifically weil das the needs of in E-road bike. That method it’s auch early to crown a definitive winner. Instead, we comment on our experiences and results with die most relevant concepts and designs at this time available. In turn, you’ll be able to identify the E-road bike system that ideal fits you and your needs!
