When evaluating the acquisition of an electrical car, three elements are likely to take precedence above all others: value, vary and efficiency. Historically, EVs have price an excessive amount of, not gone far sufficient and been saddled with uninspiring efficiency as well. Fortunately, that is altering, with vehicles just like the Tesla Mannequin three and Chevrolet Bolt EV rapidly placing these fears to relaxation.

What was true for vehicles was additionally true for the primary era of electrical bikes to hit the market — insipid bikes that may get you to work on time, however provided that the route into the workplace was principally downhill. However that, too, is altering due to rides like this, the Zero SR from Zero Bikes. Its value is in step with fashionable superbikes, it guarantees as much as 202 miles on a cost, and it has far more grunt than your common massive superbike.

Is that this the proper two-wheeled EV, then? Not fairly.


Highway-oriented bikes could be broadly break up into two fundamental classes: cruisers and sportbikes. The first deciding issue is the place your toes are. Are your boots up entrance, hanging out within the wind? You are on a cruiser. Are they tucked up beneath you? Then you definately’re most likely on one thing most individuals would think about a sportbike. (In equestrian phrases, it is much like the distinction between a Western and an English saddle.)

The Zero SR, regardless of the racy-sounding “R” within the title, really sits someplace in between the 2. The look is unquestionably sporty, however the using place is upright, with a large, comfy seat and pegs that transfer your toes ahead.

The look is unquestionably sporty, however the using place is upright, with a large, comfy seat and pegs that transfer your toes ahead.


It splits the distinction in different areas, too. It definitely accelerates like a sportbike, a middling 70-horsepower determine rapidly overshadowed by 116 pound-feet of torque — greater than all however the largest of superbikes. Its curb weight of 414 kilos can also be on par with massive sportbikes, however the no-name, single-sided entrance brake disc factors to extra humble efficiency.

The Showa suspension is absolutely adjustable, however out of the field it is undoubtedly tuned for consolation, whereas the Pirelli Diablo Rosso tires are a strong selection for spirited using.

Efficiency is unquestionably good, however among the elements do really feel a bit price range.

On the highway

Having ridden earlier Zeros in addition to numerous electrical bikes however not the SR, I used to be actually trying ahead to my first time twisting the grip right here. So I received equipped, coasted down my driveway, pointed the nostril of the bike in direction of the open highway, and was instantly, totally heartbroken. I leaned ahead with the expectation of an enormous surge of torque, and really practically discovered myself falling over the handlebars. The acceleration was extra Prius than Porsche.

Fortunately, I rapidly realized the bike had been left in Eco mode. After two faucets on the Mode button, slightly below my proper thumb, I gave it one other twist. About two milliseconds later the entrance wheel was off the bottom and I used to be laughing like an fool.

There’s, because it seems, a reasonably large distinction between the Sport and Eco modes. Most autos provide the similar quantity of final energy no matter mode, simply altering how that energy is delivered. Not so right here. In Eco, the SR is totally gutless. I’ve ridden quicker scooters. And so you will solely wish to use it when attempting to eke out the utmost vary — one thing it’s possible you’ll end up having to do extra typically than you want.


In its default configuration, with the 13 kilowatt-hour battery pack, the 2017 Zero SR affords a claimed 161 miles. I will simply come out and say it: I could not get anyplace close to that. Driving the bike as I usually would experience both of my bikes, I may barely handle half.

That’s, for sure, disappointing. I am used to driving vehicles just like the Tesla Mannequin X or Chevy Bolt EV, vehicles that nearly all the time do even higher than their rated vary, even while you drive them like regular vehicles.

Zero does promote a much bigger $2,695 battery pack, which fills up the useful cargo compartment within the tank whereas digging a reasonably sizable gap in your checking account. That pushes the promised vary as much as 202 miles — which means you may most likely get a protected 100 miles using usually.

Or, you may as an alternative go for the $1,995 charging pack, which places a level-two charger up within the tank, letting you go from zero to charged in about two hours. By default, a full cost from empty on a 110 outlet will take about 9 hours.

The storage cubby within the tank is useful, however it is best to most likely decide to fill it with extra batteries.

It actually did not take lengthy for me to understand that I wasn’t going to have the ability to come near the Zero SR’s marketed vary. About 40 miles into my first experience, the truth is. Once I observed the bike was already all the way down to 50 % cost I informed myself I might higher take it straightforward.

For my second experience I had about 50 miles to cowl, with a brief stretch of freeway in each instructions. I left the bike in Eco, pressured myself to be mild accelerating away from each mild, drafted as a lot as I safely may on the freeway, and simply barely received residence with 5 % exhibiting on the show. That is nicely into correct vary anxiousness time.

However, after I wasn’t worrying about vary, I actually loved the bike. The storage compartment within the tank is useful, sufficiently big for a smartphone, pockets, gloves, and a bottle of water, and the suspension, seat and place are all comfy sufficient for longer rides — rides of the type that sadly would take you nicely previous the vary of this factor.

That stated, whereas the Zero SR is partaking for spirited using, I’ve to say I by no means actually received comfy actually pushing it. The dealing with was only a bit too obscure, and the pulses coming by means of the bars from the noisy, single-sided entrance brake disc did not encourage confidence, both. A single-sided disc on a motorbike that weighs this a lot and begins at $15,995 is a bit disappointing. The regenerative braking does assist alleviate the necessity considerably, however not sufficient.


The Zero SR is a sporty machine and an attention-grabbing combine, providing extra consolation than your common sportbike, to not point out a patently thrilling quantity of torque. It may make an amazing bike for commuting or spirited rides on easy, flowing roads. The issue is, you will need to maintain these rides quick — or be additional considered together with your proper wrist. The state of affairs improves considerably for the 2018 mannequin of the bike, which steps as much as a 14.four kWh battery pack and a theoretical 179-mile vary, however the Zero SR wants one thing extra important to utterly abolish vary anxiousness.

For me, bikes are about leaving your worries behind and going out to have some enjoyable. The Zero SR is certainly enjoyable briefly doses, however I discovered myself spending means an excessive amount of time agonizing over the battery indicator on the sprint. Signal me up when this factor can get me 150 miles on a cost when ridden arduous. Till then, I will have to stay with the ol’ suck, squeeze, bang and blow routine.
