Could be interested in an Atherton e-bike - but only if it was both:

  • Made in the same way as the Atherton's A series bikes.
  • Not a full-fat bike, but a a light e-bike that weighs 18kg max.

The promo shots Atherton has released - looks more like their S series models in terms of engineering.

I loved Rapid Rise, seemed to be a much for sensible use of the mech spring. Very quick to adapt to it as well...

It's an S-series - S-170, Avinox motor, 3 builds starting at £7k, middle £8k, top £9k

Avinox? Yawn. It’s got to be the best motor option for their marketing/sales team though.

To be fair that’s competitive in the market place.

 

Looks like an external battery. I hope it’s removable I’d be intrigued to see if it looks as ugly as the Cotic

It states integrated (not hot removals).

 

Which is a good thing. The world doesn’t need another bike like the Cotic.

Ah ok it looked external in the vid cad bits

 

Where can you find specs ?

 

edit: now all on their website…

 

although they do not confirm battery size. Is it the same on all Avinox bikes?

Edit : it is 800wh 3.74kg or 600wh 2.87kg

 

Its certainly not going to be at the lighter end of ebikes

Hopefully they will do a shorter travel in future. 180mm is too much for what I want

Unless your bike lives indoors or you have a heated garage/shed/electric blanket to wrap around the downtube then removable batteries are a must for our climate. Lithium plating will occur on any lithium ion battery that gets charged up in an environment with an ambient temp of less than 8 degrees celsius. Unless you're not arsed and are one of those who only keeps a bike 18-24 months before selling it on the damage won't really be noticeable until a bit further down the line.

But yeah I agree there is methods of having removable batteries that isn't as offensive looking as the cotic, I like whytes approach where it slides in from underneath the down tube.

Thats interesting to know.

 

We are lucky that we have a big kitchen so my eeb has predominantly lived in the kitchen since new, and gets charged in there.

 

I am sorting some storage in the garage though, its joined to the house and has the boiler in there so hopefully doesnt get too cold.

 

Re removal battery - before buying an ebike I was against removable as it adds 500g or so for the extra stuff needed to make it removable. I would now totally sacrifice 500g for a battery that could be taken out to be charged. Also means you could fly with your bike.

 

Defo is something that manufacturers should do more, but maybe even in this case its down to the battery supplier, not the frame builder

£18 for a heated blanket thing for wrapping around the downtube/battery for charging in a colder climate - stupid Amazon link.

On the Atherton, all that info and not a single mention of weight (unless I missed it). Weight is key for me on an eMTB - only ridden a small number but I chose to buy a mid-power 20.5kg eMTB. Will the S170e be lighter than an Amflow PL? Unlikely I guess being alu and built to take a beating from an Atherton...

Looks like it could be a contender for best ebike of 2026 then! And the price actually seems pretty reasonable for what it is. Being an Atherton it should have sorted geometry and ride feel (they don't seem like the kind of people who'd settle for "just ok"), with what seems to be the best motor currently available. I'm still not in the market for an ebike unfortunately, but would love to have a go on one of these!

There are rumours of new Avinox batteries due soon, the tech hasn’t moved on in a way that they can make needle moving differences, but supposedly they will be 700/900wh.

I think you saw the part where they show the new range extender.

Google suggests the following for weights:

Avinox motor is around 2.5 kg, 800Wh battery about 3.5kg.

Standard S170 is around 17.5kg.

So looks to be around 23.5kg??

I must be in the can’t be arsed club then, as we have 4 e-bikes in the garage & I’ve never once given a thought to any of the above.

One of them is a 6 year old Trek Rail, which is coming up to 24,000km on its original battery & motor, which we use as a nursery commuter bike. I think the only thing holding it together is mud now - it’s so mistreated it doesn’t even live inside the garage, it spends most of its life leaning against the wood shed & if it needs a charge it gets chucked against the wood pile & charged there.

The battery is removable apparently in a similar way to the Whyte at least that's what it says in the Pinkbike article

Batteries are movable from all e-bikes . Most it’s not a design feature though ie designed to take the battery out to ride / travel

 

Most it means dropping the motor and not cocking things up

 

If it truly is removable then that’s a huge positive

Battery on the Whyte Kado is fairly easy to remove. Pull the rubber bung out of the catch on the skid plate battery cover, pull the catch, open the cover, disconnect the connector from the battery, undo a bolt, slide battery out.

@funkydunc if you remove the battery and fly with your bike what battery are you going to use at the other end?

I was also confused by the Cotic style battery so if that isn't the case then this bike will be on the list for some time in the future as a lad I know raves about his Atherton. Removable battery would also be a bonus because my garage gets cold and damp.

@Simon, I was thinking about this. The Gen 5 Bosch batteries (600 and 800wh) are standard across all new Gen5 motor bikes from what I can see, so if you were flying somewhere you could just rent a battery in the size of choice. Bike shops, resorts or bike holiday providers could set up this as a service. I think Avinox batteries are generally not removable, but let’s see.

as above it would be great if you could rent a battery at the other end

 

+ I’ve stayed places over night in the uk where I’d leave the bike in the car and bring the battery in to charge. Many places don’t let/like you bringing bikes in

Can you not just take the battery in hand luggage like you would any other battery, or are they size restricted? I fly fairly regularly for work with a bag full of camera gear and a load of batteries, never any issues there but they're a lot smaller!

I think there's a battery capacity restriction.

And that's the first batch of 50 sold out completely already!

No, I'm not one of them. Anyone on here one of the fifty?

But only for a about a week before we were told about that Merida that was the best bike of the year.

Back to Atherton, at the risk of normalising 7 grand bikes, seems a decent price when compared to mainstream brands, nevermind the Yetis of this world.

Gee talking through the new ebike.

I have to say it's a decent looker!

Looks good aesthetically, but also looks like a bit of a biffer though, even with the lightweight battery/motor. Considering the new Amflow is 22kg with Fox 36's, what are we thinking for a mid spec one of these - 24-25kg?

Like the cylindrical battery, looks tidy. Wonder if Cotic are rubbing their chins looking at that?

Doubt it - still far too large for a steel downtube that gives good ride characteristics.

atherton is a CAT5 DH rated frame remember - the amflow is a lower category frame so will be lighter because of that. The atherton will therefore be more robust.

Enduro mag have it at 24kg for the size 8.
All these releases are too heavy for my tastes but this is still.competetive with similarly specced full power bikes
The Mondraker is 23kg ISH albeit with an 800wh battery of slightly lower density.

Be good to see what Bosch & others do next. The SX range is due a v5 and is where my interest lies along with something akin to an updated TQ.

Bit of a shame that Avinox went chasing even bigger power  - to the point where it's mostly useless - instead of looking at how small and light they could make things while still getting 85-100nM 

Would much prefer "we shaved a kilo off the motor and we can use a smaller lighter batter as a result" to "you can double the power and empty the battery in 20 minutes"
