New Cotic Rocket is a steel frame ebike with external battery

People may object to the battery placement, or the external cable guides, or something else. But I know that Cy and the Cotic team will have put design effort into every bit of that bike with a view of it being usable, maintainable and rides superbly in British conditions by the average bike rider. They won’t put in integrated hidden cables just because it look pretty but you have to bleed your brakes every time you want to change your stem.  I would much prefer a bike that is functional and rides well to one that just looks pretty – and we know that skinny steel tubes just look right.

They are supporting British manufacturing – this has to be a good thing.

Best of luck to them.

@StuF Thank you

I’m not looking for an ebike in the forseeable future, but I appreciate how Cy has explained the reasoning behind the design, and has come on here to a partly sceptical audience to address specific questions and concerns. It’s all very interesting to see behind the curtain like this!

fairy muff, personnally no one I know (e-bike owners) would ever spend money on a shimano powered bike. Even brose has a better rep, go on throw an email at DJI… everyone wants one of them

So you know no one with an Orbea (Rise) or a Vitus or a…?

Only if they do them with Lewis brakes.

I couldn’t begin to afford this, nice as it is, but I think the best part of all, is that you are all able to interact with the owner of the company directly on here. It’s very refreshing 🙂

Waves.

Is there going to be a C1 ( or smaller) version?

Yes. Only three sizes of these final prototypes were made, as that’s what the COTIC peeps ride, but all 5 sizes for production. C1 being made. Size charts and geom tables on the COTIC website.

I’ve not ridden one yet. I’m C3 which happens to also fit interested journalists, so not had a chance.

Gone a bit mad with the finish options… going to be a choice of the three best colours COTIC have ever done (in my entirely biased opinion) or can pay £50 more to get any of the other UK colours. See the colour chart on the product page (in the a la cart colour tab).

There is probably an ebike in my future. Is this it? I’m not sure, but it’s hard to argue that extra choice is a bad thing. This really is choice, not clone. I’m certainly not put off by the weight or looks. The idea of a removable battery makes total sense to me, Particularly if they are a standard battery. That opens up flying with the bike and renting a battery on arrival. It would make life so much easier away from home in the uk just needing to get the battery to a socket

Here’s a genuine question. If i bought a standard Cotic bike i wouldn’t be researching the warranty. I’d assume that chances of the frame having a fault would be small and if it did I’d put up with a return of the bike or frame to Cotic.

With an ebike I’ll be a bit more cautious. Because the risks and complexity are greater. So if i buy a cotic ebike and there electrical issues will i be able to use a local Shimano service centre for support?

Congratulations, Cy and team. To my eye,  that’s a good looking bike.

I find the external battery no more offensive than a frame bag or loaded up accessory mount and the benefits brought by having it out in the open bring some useful versatility to the bike.

Would there be a possibility of using this layout for a lighter version that you could use as a normal bike ?

Use a fauza motor or the one that the trek sl uses and then you could whip the battery off and have 2 bikes in one .

I think the whole this is what we want so this is what it needs to look like design ethos is great . You might not like the outcome but every decision can be justified and I bet it looks better in real rather than just photos .

Having seen them in the metal a few times over the last couple of months when visiting the warehouse, visually the battery gets lost very easily against any kind of background clutter – the bulbous gubbins round the BB is more of a giveaway that its an eeb.

Personally I’m more excited to see what that suspension design looks like on a proper bike without all the ebollocks getting in the way – I think that’s going to make for a very, very, pretty bicycle.

Cotic have put out a little video of them riding the prototypes – I can’t figure out how to embed it but it’s over here on the product page: https://www.cotic.co.uk/product/rocket#video

With someone on the bike the battery almost vanishes amongst the legs and kneepads that are constantly either side of it.

Even without someone on the bike, the more you see it the more innocuous the battery lump looks, like getting used to MTBs having bottles again. Obviously it’s not for everyone aesthetically but it’s a steel full-sus, and they’ve never been a mass market thing.

My old (gen 2) alloy Levo has a similar build kit and travel (nothing carbon, Lyriks, etc) to the base model Rocket and a 500Whr battery and it weighs bang on 24kg. Recently I’ve ridden it without the battery, which takes it down to 21kg and it’s quite a lot spritelier feeling in terms of handling (but harder work/slower uphill!)

Looks pretty similar to a Swarf Contour.

I don’t mind the look if it as you don’t really see the battery and just see a steel framed full suss bike, unlike most ebikes that have massive fat down tubes.

Unfortunately it’s stupidly expensive. British made or not that’s silly money.

To be fair the battery looks no worse than a rear mudguard and plenty of people run those with no shame.

That’s nice…..I think. It’s taking a tiny bit to get my head around the battery – I think it’s just that early ebikes had an external battery, then they got all svelte and integrated so this initially looks like a retrograde step. Then you think about it some more and especially when you think about different batteries and it makes sense again.

Sadly, it’s all just theoretical as I’ll never be in a position to afford that sort of money even when the time comes when I consider an eMTB. But then again when I last bought a proper bike I had to back out my desire for a Cotic and settle for a Bird because of $$$. I hope there is a market who can justify this much on a toy…..with looks that won’t wow their non biking mates. Not that that should be a factor, though I suspect it sometimes is.

I love the background stuff, and I see teh rationale, but the looks would just put that right off my shopping list, if it weren’t for the price already doing that. I mean, I loved how my rocketmax looked, and my Solaris, and my Soda, I did NOT love how my Hemlock looked it looked like one of those wooden swingbridges they have in France, but I did love my Soul and my other Soul and my other Soul. But this, no. I think the steel looks and the ebike battery are just basically incompatible and this is probably about the best it can be, and still orrible.

I’m certain it’ll ride brilliant. But other bikes ride brilliant too.

The silhouette reminds me of the Swarf Contour which was a beautiful looking bike. I’d be interested in a normal/not ebike version if I had the cash. I have an ebike for commuting but still prefer a normal bike for fun time.

Once I got over the ‘looks like a conversion’ thing the design has grown on me, the pictures of it being ridden the battery gets lost and the frane looks quiet elegant. Somehow we’ve normalised the mahoosive fugly downtubes on most ebikes so it’s good to see something different.

Me this lunchtime when I first saw it: OMG what on earth were they thinking.

Me this evening: I’d love this bike for the outrage it’s causing alone, both today and in future if anyone spotted me riding it.

The only things that kill it for me are price, Shimano motor, and no room for water bottle inside the front triangle on the smaller sizes.

So you know no one with an Orbea (Rise) or a Vitus or a…?

I know someone with a Vitus. I believe the warranty been useful (at least twice).

As I’ve mentioned on a FB page, it will be very interesting to try one and see if it rides like an mtb with assistance when needed or like my Giant E Trance which is awesome fun but rides like a downsized lighter, pedal-able Trailbike that will just plough through whatever scenery I throw it at. Once you see the ERocket in the flesh and get over the hunk of battery sat there, it is actually a work of art, that should be an absolute hoot to ride. Very eager to have a blast on a C1.

Chapeau folks.

I used to own a Shimano motor and now I have a Bosch.

IMO there’s not much in it. Neither are fixable or maintainable anymore. Both use closed systems so you have to visit a dealer to do most things (e.g. fit a different sized chainring, find out what the error message means).

Tbh once a motor is out of warranty, just send it up to Emotor repairs in Barrow in Furness and let them work their magic on it.

No idea why they’re so different, but the 630Wh external is 0.5kg lighter than the internal one we have.

@Cy – Maybe its due to heat dissipation

When (or IF) this MGU ever comes to market it could be in an interesting option. Mounting pattern is Shimano EP8, which (I think) is the same as the new 801?
UK developed…… They have been running an Orange as a test bike……

Back in the day it was easier to find a thread that had Brant on it than one that didn’t. 🙂

I like it, I think the attempt to try to make E-bikes look like normal bikes by making the downtube a bit fatter makes them look heavy to my mind. At least this doesn’t try to hide what it is, plus it kinda looks like a big waterbottle anyway.

Both use closed systems so you have to visit a dealer to do most things (e.g. fit a different sized chainring, find out what the error message means).

Really?  Shimano owner here – chainring needs a tool (the same one that fits rings to Shimano’s XT cranks now) but a different chainring would not require any software changes.

The Shimano mobile phone app gives end use the error codes which you can find  on the Shimano site.  Many of the error codes are pretty useless – there are multiple codes that are just described as ‘sensor abnormality in drive unit’ without telling you ‘WHICH’ sensor is giving an issue.  Some are more useful – eg speed sensor issue.   The dealers don’t actually get any more info connecting it to their computer than you can get yourself.

The more I look at this, the more I like how it looks! It’s really not that different to an enduro race bike with everything strapped onto the frame, and then the look of a gearbox where the motor is.

I kind of like it. The bit where people are criticising the aesthetics is mildly hilarious given that the average e-mtb looks like the cycling equivalent of an anaconda that’s inadvertently swallowed a small water buffalo.

No Guy Kesteven links yet?

Although he does remind a bit of the guy from the fast show who thinks everything is ‘brilliant!’

Not really any point when you already know the outcome.

24hrs later I think the best word for this is “jarring”. I’m sure it’ll work well, and the setup will appeal to a certain crowd, but it’s a real surprise to see a bolt on battery come back on an expensive frame. Especially, and this certainly isn’t Cotic’s fault, the battery cover just looks cheap.

Looks and cost aside, I like it. But my opinion on this bike is about as relevant as my opinion on the latest Ferrari, as I can’t afford one of them either (can replace Ferrari with most sporty cars to be honest).

Had 24 hours to ponder this and still think it looks awful! E-bikes are ugly and this is an ugly E-Bike that looks like something you’d find in Halfords or Decathlon. Always amusing to see the lengths that STW members go to to defend Cotic’s honour though 😉

Sure it’ll ride well though.

Well if he ever criticised anything his YouTube gravy train would come off the rails. His videos are alright if you want a close look at a new bike but they’re worthless as actual reviews.

I like its direction, personally I’d never buy a bike with a fixed battery (hotels, holidays and poss winter storage), so external seem sensible to me, as does different size batteries and esp rucksack sized spares, I think headset cabling and internal cabling is something that suits designers more than owners however weight is a problem and for me so is the Shimano motor (based on my personal experiences) , let’s see who brings out what next.
