A Very Clean 100% Electric Chopper.

1Sinecycles2Sinecycles3Sinecycles4Sinecycles5SinecyclesThe story of early electric motorcycles is very old and somewhat unclear (first patent for an electric bicycle application seems to be on September 9, 1895 in Canton, Ohio) and it took them more than a century to belong to our present. As soon as they become cheaper and more practical by offering a wider travel range than a daily commute, there is no doubt than their market share will increase at a very fast pace.

5bisSinecyclesSwiss-based Bruno Forcella from Sine Cycles shares the ambition of all his fellow custom builders, to build something very different. Bored at the idea of always trying to best another builder’s amazing V-Twin creation, he went the way many others will go during the next decade. Building an electric custom bike from the ground up, using the current electric motorcycle manufacturers’ technology, but in a rigid chopper frame. A custom to be emissions free but still good looking, faithful to the classic chopper aesthetics.

6Sinecycles7SinecyclesForcella sourced all the electric parts at Zero Motorcycles and was lucky to have his purchase approved, Zero usually not selling their proprietary parts, only their completed models. Of course, it was out of question to try to hide the electric motor, the drivetrain, the battery housing and heat sink in an open chopper frame. Instead, Forcella show them in a set up and layout quite pleasant to the eye. A design I am tempted to call “Electric Zen”

8Sinecycles9SinecyclesWith no clutch to operate, gears to shift and full torque immediately available, this chopper has accelerations equal, if not better, to many gasoline powered motorcycles. Yes, limited range – in this case about 40 miles depending of rider weight and riding style, makes this chopper more suited for commuting or for occasional rides around town. But no maintenance required and no real risk of being stranded: a smartphone application provides detailed information such as time until charged, average watts per mile, total charge cycles and much more. Because batteries technology is progressing extremely fast, impediments to electric motorcycles, price and range, are going to disappear. In the next couple of years expect more well known builders to show their electric interpretation of a Chopper of a Bobber, of a Cafe Racer, of a Bagger, etc. So, welcome to the future of motorcycling… Sine Cycles.

    Proof that not all electric motorcycles have to be ugly. Congrats for the effort.

  5. 5 TJ Martin Feb 2nd, 2015 at 9:13 am

    ‘ Clean ‘ design ? Perhaps . Though I’d say its closer to being downright boring , trite and inane . ‘ Clean ‘ running though ? In light of the pollution created by the manufacturing of the drivetrain [ rare earth minerals etc ] – Li Batteries and all the accessories needed to keep the batteries cool in the heat / warm in the cold [ it does have that does it not ? If not … guess what ? Below 38f the batteries begin to fail .. above 81f the batteries begin to fail ] – along with the pollution created in order to charge the thing – as well as all the multiple and quite serious disposal issues [ remembering those batteries won’t last more than 36 months at best ] ….. and the simple fact is this bike spews out as much if not more pollution over the span of its life [ cradle to grave than a full on heavyweight twin ICE chopper tuned to the hilt . And thats fact !

    Not … the persistent ongoing Myth of the E/V being perpetuated by those with an agenda . That agenda not being to be ‘ Green ‘ …. but rather to make the ‘ green ‘ 😉 …. filling they little wallets on the backs of an uninformed public foolish enough to buy into the whole E/V mythology

    E/V’s . Same as they were [ with a few added on gee gaws ] back in 1901 … same problems … same issues …. and the same ultimate outcome …

    Fail !

    Finally, a good looking electric.

  7. 7 JackS Feb 2nd, 2015 at 9:19 am

    Now that is how an electric motorcycle should look! A simple, clean, in-you-face design declaring, “hey electric motorcycles have arrived!” Is there room under that tank for more power storage?

  8. 8 .357 Magnum Feb 2nd, 2015 at 9:44 am

    TJ gets a lot of stuff wrong in his critique:

    “Pollution created by the manufacturing of the drivetrain [rare earth minerals etc]”

    Rare earth minerals are not inherently more polluting to extract from the ground than iron and aluminum.

    “Below 38f the batteries begin to fail .. above 81f the batteries begin to fail”

    No, they don’t “fail;” they just have reduced energy capacity and thus reduced range. His wording is intentionally fearmongering and wrong.

    “this bike spews out as much if not more pollution over the span of its life”

    That’s purely depenedent on the feedstock used for the generator: if it were all coal, he might be right, but guess what? We have been replacing coal with cleaner natural gas and renewables at a crazy rate over the past few decades. TJ is several decades out of date, and wrong, wrong, wrong.

    “And thats fact!”

    Insisting that something that’s several decades out of date is “fact” doesn’t magically make it less false.

    “rather to make the ‘green’ …. filling they little wallets”

    TJ is apparently unaware that every motorcycle manufacturer in business today is a for-profit enterprise. Yes, the builders of e-bikes, just like builders of ICE bikes, want to make money, but unlike greedy socialists, they seek to do so by offering us something we want in exchange. Sorry TJ missed the basics of capitalism back in elementary school.

    Well, this bike is something *I* want. Unlike TJ, I know about the battery advancements that make the current crop of bikes “same problems… same issues…” If he thinks lithium-ion batteries suffer all the shortcomings as the century-old lead-acid technology, let him be blissful in his ignorance. Just don’t actually think that his *having an opinion* is the same as *having an INFORMED opinion*. He’s absolutely out of touch.

    @ .357 Magnum
    I agree with your post 100%.

  10. 10 BobS Feb 2nd, 2015 at 10:18 am

    TJ….the liberal tree hugging enviormentalist so concerned about wether or motorcycle polluts or not. I’m sure someone so concerned with pollution rides a Schwinn back and forth to work at the hemp skirt factory right?

  11. 11 The Vintagent Feb 2nd, 2015 at 10:21 am

    TJ is an excellent spokesman for the oil & gas industries! And also very much wrong, as pointed out above.
    Both conventional and electric bikes require that stuff from the earth gets mined, refined, manufactured, and shipped. The difference is in how their juice is supplied; do we try the increasingly home-grown, non-extracted electric power, or carry on dealing with foreign suppliers or risk poisoning our land?
    As we rode across the US on the Motorcycle Cannonball last September, there were 2 hotel stops where we were handed bottles of water at the front desk, and told to keep our showers short – the local water was contaminated. This was red-state heartland!
    Electric vehicles are hardly ‘in the same place as 1901’ – seen that video of a Tesla blowing off a hotrod Porsche? Yow.

  12. 12 GT-UK Feb 2nd, 2015 at 10:47 am

    TJ Martin: unfortunately, just stating something on a forum does not make it a “fact”, merely an opinion. To be considered as a “fact” it is necessary to at least quote the verifiable source of information on which the “fact” is based.

  13. 13 qajaqr Feb 2nd, 2015 at 10:53 am

    I would only add to this by saying anyone that casts dispersions regarding ‘facts’ back them up with a reputable, trackable source. Pulling numbers and ‘facts’ out of the sky when discrediting another’s work smacks of pettiness and an affectation of superiority.
    Impressive and unusual electric motorcycle, by the way, Mr. Forcella.

  14. 14 Clark Kirkendall Feb 2nd, 2015 at 10:59 am

    Lets leave the political bickering aside and remember we are all here because we love 2 wheelers!
    Arguing about Red and Blue is what is messing this country up and neither party is really looking out for us. Just ride what you like and be glad you have the choice. I personally will choose to burn gasoline and am not jumping on the electric bandwagon yet, but I like all motorcycles.

    If there was only one Honda 50 around, we would all be waiting in line for a chance to ride it!

  15. 15 IAN SOLLEY Feb 2nd, 2015 at 11:03 am

    i am all for electric bikes and if the Livewire gets made for a sensible price I will get one as where I live in SE England range is less of an issue for everyday riding, and I think it looks amazing as a modern Hi Tech bike

    What I don’t see is the point of putting new electric technology in an old hardtail bobber set up, if I want to ride around town on a hardtail I want it to be a noisy smelly old V-Twin, that has some style and appeal and this just looks like a big kids toy.

    Rol on the next one.

  16. 16 fuji Feb 2nd, 2015 at 11:23 am

    Very unique and appealing. It will raise the eyebrows of production manufacturers who possibly will want to claim the design in the future.

    Great ingenuity. I would like to have it.

  17. 17 fuji Feb 2nd, 2015 at 11:30 am


    [looks like a big kids toy.] Noisy smelly old V-Twin

    The right words

  18. 18 John B. Lurvey Feb 2nd, 2015 at 11:33 am

    One fine looking machine. I especially like the looks of the seat. Reminds me of the old days. Good Luck with sales.

  19. 19 aldo vargas Feb 2nd, 2015 at 11:48 am

    We are almost there… to the era of clean energy.

    I think that 120 Km/h is more than enough of what people actually run on bikes.

  20. 20 Clean Dean Feb 2nd, 2015 at 1:32 pm

    What is the cost? I am very interested. I work 12 miles from home and would love to moto it around Southern California

  21. 21 SIGFREED Feb 2nd, 2015 at 2:15 pm

    Great, nice, gallant effort, innovative thinking, the future..??? Uhhh, on my knees, heavens above, if it is – may we humbly just be blessed with the use of the internal combustion motor for just one more decade – PRETTY PLEASE!

  22. 22 Blackmax Feb 2nd, 2015 at 4:45 pm

    Clean looking, yes….
    Clean running, yes…
    For me, No !!!
    I like my gas powered V-Twin
    Thanks, but, No Thanks !!!!!!

  23. 23 Steven Feb 2nd, 2015 at 5:45 pm

    I like it. If it has a reasonable range and price, count me in.

  24. 24 Lyle Feb 2nd, 2015 at 7:18 pm

    Somewhere in history, Oh about 115 years back, there was a guy shoveling out a horse stall who was down talking the new fangled petroleum engined bike….

  25. 25 Pop Feb 2nd, 2015 at 7:18 pm

    Following is opinion. Opinions resulting from five decades in the saddle but opinions nonetheless.
    Great effort. Boxy though, and without pipes or cabling or some softening counterpoint the angles of the motor bay are over pronounced. Even the round generator adds a geometric rigidity to the bay. Still, the bike is clean as a whistle without all the geegaws that adorn gas mills.
    Chopper styling is a sage choice. It is easier on the eye and more familiar to many riders than the electrics manufacturers are offering. Granted they are not marketing to motorcycling traditionalists but this machine and ones yet to come will bridge a gap and my hat is off to Zero for making their machinery available to a custom build. That’s good business. It puts Zero on the map to customizers and those of us that like our motorcycles lived in. Somewhere some 18 year old kid sees that bike and a couple of synapses fire that wouldn’t have had it been a Zero SR or one of the other plastic encased Zero models instead. I’ll be dead when he’s whittling away at some build that either by necessity or choice is powered by a stator and armature. The outlaw lives on.
    Lastly what is missing entirely from this conversation is that electrics are fast. Stupid fast. Torquey and stupid fast. Range is a big limiter currently but that is indeed going to be moderated by both technology and the logistics of fast charge and/or battery swap stations. Smoking tires is smoking tires. Gas or go juice, the stink of hot rubber is the same.
    Get ready TJ. Here comes tomorrow whether you and I are ready or not.

  26. 26 nicker Feb 2nd, 2015 at 11:03 pm

    A motorcycle -Yes-
    Interesting -No-


  27. 27 Zenaldo Feb 2nd, 2015 at 11:10 pm

    Sorry folks…give me an S&S 143 any day…just sayin…but kudos to these guys for at least trying to enhance the overall look of the new beast..another “lipstick on a pig” deal as far as Im concerned…40 miles isnt exactly a long ride day…

  28. 28 nicker Feb 3rd, 2015 at 12:48 am

    Whatever it is that makes motorcycles so compelling…..???
    It’s missing in this instance, for me anyway…….


  29. 29 Sportster Mike Feb 3rd, 2015 at 5:44 am

    Finally a good looking leccy bike…

    I have seen a guy here in England putting electric motors in old Honda CB200s etc ( ie anything with a blown engine or gearbox) but of course it looked like what it was a half a hybrid etc – a good idea nonetheless

    This looks good – just needs suspension for my bum..

  30. 30 Boomer Feb 3rd, 2015 at 7:22 am

    I guess it was bound to happen. A blend of old and new technology with the chopper/bobber look thrown in.

    Is that thing as tiny as it looks with the picture of the guy standing behind it? If so; anyone over 4′ would be too tall for it.

  31. 31 Clarke Feb 3rd, 2015 at 7:29 am

    I love this website. That said, if God intervened and posted a perfect motorcycle, the first ten posts would be from people saying I don’t believe in God, I don’t believe in God-made motorcycles, or God isn’t a real biker.

    This bike is a very creative application of an emerging technology. I think it’s great to see it and learn about it on this website blog. Thank you Cyril. Without this website blog I would likely never have seen this.

    One other thing, the other Clark here is right. We are here because we love motorcycles. If the only model was a Honda 50 (and it was the only motorcycle at one time in many of our lives), we would be lining up to ride it.

    Have a great day everyone.


  32. 32 nicker Feb 3rd, 2015 at 1:23 pm

    “… if God intervened and posted a perfect motorcycle …”

    I guess that depends on your perspective.
    If all you want out of motorcycling is transportation from A to B…. then -Yes- “a perfect MC” would do.
    But so would a buss.

    On the other hand if you want a challenge, a creative outlet, and adventure.
    Even if God created it…. Sorry, i don’t see that here…..


  33. 33 Steve Berg Feb 3rd, 2015 at 4:16 pm

    Okay. That’d do for my daily commute!

  34. 34 Andrew Feb 3rd, 2015 at 5:28 pm

    I understand that in the future we will have to abandon petrol engines, but could we keep the suspension?

  35. 35 nicker Feb 4th, 2015 at 12:02 am

    “… I understand that in the future we will have to abandon …”

    Who’s this “we”…… You got a frog in your pocket….???


  36. 36 Sheridan Feb 4th, 2015 at 1:38 am

    Looks great, well done!

  37. 37 jeff willman Feb 4th, 2015 at 2:43 am

    It’s a great idea and all but i would be afraid to ride it in town because unlike the v-twins we all know and love these things have no rumble to them. Who’s going to hear you making them look for a bike? If you ask me you might as well paint a target on your back with hitme as your license plate.

  38. 38 Pop Feb 4th, 2015 at 5:43 am

    There is a sound standard being developed here in the states. I don’t know where it is in development but the point is to make any noiseless vehicle audible to pedestrians. It’s another hurdle, not a showstopper.

    I’m going to run out the clock getting my kicks on a fire breather and I am fine with that. Vtwins are the machine of my time. My time is passing though and a new day is dawning. Maybe electrics are not the answer but if motorcycling does not test its boundaries and customizers don’t go down new paths then sameness may be what kills my way of life before the safety nazis ever do. I’m about bored to tears with hot wheels, effy controllers and four digit exhaust systems.

    Pop would rather swap lies with a guy who crafts pushbutton motorcycles than one who buys factory customized vtwins.

  39. 39 nicker Feb 4th, 2015 at 5:43 pm

    “… swap lies with a guy who crafts pushbutton motorcycles …”

    Its not the “guy who crafts” …… there won’t be that many.
    Its the “guy who buys” such a contraption you’ll more-n likely be dealing with.
    What would there be to talk about….???

    My point is simply:
    “[he’s] from Mars, [your] from Venus”
    Two completely different MC experiences


  40. 40 nicker Feb 4th, 2015 at 5:47 pm

    Can you imagine playing Golf with someone who shoots a ball from an air cannon, then has a GPS guide it into the cup…….????

    Just saying.
    Two different experiences.


  41. 41 Larry Wolf Mar 17th, 2015 at 12:51 pm

    Those extremely low bars look out of place unless your building a TT racer for the dirt track. They should be raised up at least 6 inches because it looks like it would take 10 foot arms to reach them and be very uncomfortable–the opposite of a Victory laid back ‘cruiser’. I doubt this will ever see the light of day especially without a rear suspension and a more comfortable padded seat. No thanks. Range way too low too because EV bikes can easily reach 150 miles with OLD battery tech. With current battery tech they could reach 200 to 300 miles easily.
