Achieved by having a tiny 9s*3p = 27 cells battery...

So about half the number of cells of a standard ebike.

So 1.25kg battery + 1.2kg motor give you an extra ebike kit for 2.5 kg.

Achievable for a third of thr price with a road bike at 10kg

If the claimed range and performance are true that's a pretty impressive spec. I don't know of any conversion kit for a road bike which would achieve what they seem to be setting out to do which is to make an E bike look as indistinguishable as possible from a 'regular' bike?

Every now and then, someone has a go at re-inventing the bike. This take on an EAPC isn't exactly original but at around 12 kgs, it's up there with the lightest assisted bikes I have seen.

Usually, there is a problem; some real-world drawback which causes these machines to fail the marketing test and that's why they never become ubiquitous. In the case of this one, the first problem is the price as few people in the market for an EAPC are likely to be willing to part with the mark-up price for such a spartan machine.

Machines like this may be deemed 'cool' in San Berardino but I'm not sure they'd receive the nod of approval from the good folk of Huddersfield or Hull. 'Loadsa dosh and ye don't even get mudguards or a bell or lights!'

Of course, I may be missing something and our venerable pedelec dealers, who know a thing or two about what sells and what doesn't, could be stocking up with their first consignment of these bikes right now.

Bring on the next invention please!

Their range "estimate" of 44 to 62 miles is nonsense for most, only the very fit could achieve that from the 10Ah battery. Comparing it with the A-bike really exposes how poor it is, that miniature folder being hardly a valid comparison.

And I doubt very much torque from that tiny diameter motor, and they are reticent about that. They give the wattage as 500 maximum but don't say if that's the gross consumption or actual net power from the motor.

I see it as competing in the same specialised market as Cytronex, the very fit cyclists who want the odd occasional application of help on the climbs, but there's very few of them.

Interesting how the product description, differs from the photos and the listing.... images show 105, yet the description in a photo states Claris and yet the listing says 105. Image shows 105 canti brakes, yet the photo desciption says center pull, and the listing states 105, and then tyres types listed as Kenda or Maxxis. Cant say much about the tyres, i think they will be much of a muchness, but theres a massive difference between 105 and Claris. Theres nothing wrong with Claris, even the top of the spec Speciialized carbon framed tarmac comes with Claris on the entry level machine, but I would have to expect 105 and get Claris. That being said, buyer be aware and all that. Good to see another race style bike offering, and this one with a carbon fork.

annad will build the bikes with the components you want, if you don't mind waiting 4-5 months for delivery.

Looks like a re-badged Annad to me:
It's nice to see you still have a read of these pages Dave without finding the need to suggest remedies for everybody's electrical ills, particularly those whose problems could, and should, be sorted by their seller.

Your comments on the abilities, or otherwise, of the hugely increased volume of EAPCs now available are always welcome as so many 'reviews' by owners here tend to be hugely subjective, really lacking the objectivity of someone who has ridden a wide variety of machines, in addition to building and modifying bikes at one's own expense.

As for the Annad or Freygeist bikes, I'm sure those tiny motors provide sufficient kick to endow the bikes with a fair turn of speed from a standstill up to the legal cut-off speed but as Flecc has suggested, the mileage claimed is probably a little fanciful. That in itself will probably deter many prospective EAPC buyers even though I'm sure the vast majority never ride more than 10, maybe 20 miles a day or each time they ride.

Lightweight bikes are great and have no real downsides in my experience. My old Cytronex still goes well, is simple to mend should things go wrong and does everything my other EAPCs do with the added bonus of being ok for roof or tailgate rack mounting. Obviously, for those hardy types who require to spend hours in the saddle, then mileage anxiety is something they really don't need. Either they carry a spare battery or buy a heavier bike with a more capacious battery.

Mudguards, pannier rack, lights and chainguard are all important to me but perhaps not to others so any bike I own needs to be so equipped. I'm basically a fair-weather cyclist but the weather is unpredictable!

Been a while since I posted. I played around with the Keyde motor on my Brompton Ti for a while. That was down at less than 12kg with a DIY 1kg, 36v, 3Ah battery. Will easily do a 10 mile round trip in flat Cambridge (I make most use on windy days). Could probably get more power for same weight now.

https://bromptontalk.wikispaces.com/Electric+Assist

I get one or two emails every month from Brompton owners asking about assistance and always recommend the Tongxin Nano. One of them sent me this link recently

http://www.velogical-engineering.com/velogical-velospeeder.en

I am not convinced.

In the end I went back to Tongxin Nano, the Keyde proving unreliable after six months or so. I wasn't using their controller but a programmable one with a throttle so maybe my fault.

My Brompton Ti is now motor less and used most days in the better weather.

My original Brompton conversion here back in 2009 (even that is around 15kg with battery, split between bike and bag) is still in use with original Tongxin motor and some 12K miles later. I still have about three spares sitting on the shelf and a couple of Keyde motors I should sell.

Might be retiring soon so more time to fiddle in the workshop :)

Regards

Jerry

Thanks for the update Jerry.

Must admit I was under impression tongxin was surpassed by keyde.

Appreciate the long term use pov

Love the look of the Freygeist,but crazy price.
Does anyone know how the battery is removed?
What is the capacity of the battery?

To remove the battery, you drop the forks out of the head-stock, then remove the plate on the front of the headstock, which leaves a hole for the battery to come out. It's 9.3 Ah, but only 33v (9 cells), so 90% as much capacity as a 36v 9.3 Ah one.

The range is purely arbitrary. The bike is light and efficient. Most people could ride it without power, so its range would be infinite. If you want to ride around without pedalling, it's probably the wrong bike.

I think their patent must only be on the self adjusting aspect, since Cybien in France has had this kind of friction drive for years in a dual form. Theirs has manual motor engagement with automatic disengagement at the legal limit and has to use a special deeper rim with a separate drive surface, rather than using the braking surface for drive as well:

Dave,thanks. Good to see you back,you were much missed,I value your knowledge presented in a way we can all understand,very hands on.
Where do you think they put the controller?

The controller is in the motor. Do a search for Keyde hub-motors to get more details. Keyde had a poor reputation for reliability, but they released as new uprated motor about 6 months ago. I don't know which version that bike has. the new motor is a bit bigger and heavier than the previous version. You can still buy both versions
