Hey! Thank you so much for making this review video. The bike featured in the video was one of the earliest prototypes we built last year. It features a hidden mid-drive motor seamlessly integrated near the crank within the frame. Additionally, the rear wheel is equiped with the internal three-speed gear hub, which can shift automatically depending on your speed. Our current iteration of bikes has optimized automatic sensing lights and active safety alarms. The photosensitive component will continuously detect the ambient light within 10 seconds and only turn on/off the light when necessary. Additionally, both features can be turned off via the touch screen. For the problem that the horn is not loud enough, we will increase the volume and consider adding customized functions. Of course, we noticed that what everyone is most worried about may be the riding range. The latest version uses LG's 21700 lithium battery, which has a higher energy density. It can maintain a driving range of more than 50 kilometers even on complex road conditions that alternate between flat roads and uphill slopes. Anyways, we'll carefully consider the criticisms and suggestions to enhance the performance of the C8 and ensure the quality of our products during mass production. 😄

[@WoodyWanderer]

I really like the look of this bike no wires and nice colour . The google maps built in I’ve been looking for a screen with that 😍. But the range has put me off massively as I want a bike I can do 40-50 mile rides . I already have a 20 mile one on fastest speed . Also I don’t get the automatic lights , it’s not hard to turn lights on so why make them smart which won’t work half the time ?. If you send me this bike with higher battery range I’d love to try it out ;)

[@vtmwatch2255]

​@@WoodyWanderer eheads tested a prototype with an old battery pack (18650 cells). The production is now ongoing with (21700 cells) and the range will be much higher

[@Alessandro---]

1:17 “I’m basically holding hands with Michael [Owen]” by being on a bike carrying his signature … I bow to Eilís’ elegant scriptwriting, she avoided mentioning other parts of the bike shared with a celebrity rider! No massaging seats on this bike 😂😂😂

[@denkibike]

The screen on that looks very busy for something that should be glanceable. You can add a rear radar to any bike with the excellent Garmin Varia paired with your choice of cycle computer, game changer for safer road riding.

[@Tezeusebike]

Thanks for your suggestion! We will continue to optimize the UI of the control interface.

[@markrizzofield9403]

Love the display Bike looks almost normal. I'd buy colours depending.

[@robrimell9684]

It's a lovely looking bike. Their website advises they have no dealers in the UK, so what happens if a repair is needed?

[@richardjohnson5529]

I like the bike but with regard to the warning system i would prefer a mirror, is there a good mirror fitting on the market?

[@maidbloke]

I use a mirror that clips on to the end of my handlebars, a couple of quid from eBay, brilliant little thing

[@ravenragnar]

Looks cool. Wait to see if this company is still around in two years then maybe have another glance.

[@Alessandro---]

Sigh, so true…

[@vtmwatch2255]

Vanmoof vibes ...

[@robrimell9684]

Good point! When I asked them, via their website, if it was made in China, they didn't answer!

[@raddgaming9969]

absolutely amazing

[@brookes79]

I'd be seriously interested, if it had a model with a rear cassette, as you need gears for hills & also for cycling above 15mph or downhill.

[@vtmwatch2255]

The transmission and gear ratios of the internal geared hub are discussed on their Facebook community group page. According to calculations, good speeds for sporty riders on flat (cadence 90) or normal riders doing downhill

[@fencep]

You talk about mid drive motor and film the rear hub. I extra watched the original promo video. And yeah, mid drive = at the bottom bracket. I guess the rear hub includes the 3 speed shifting.

[@Alessandro---]

lol Kol must have been distracted 😹😹😹😹😹

[@Tezeusebike]

LOL. The mid-drive motor is built inside of the frame, close to the crank. The rear wheel is equipped with an internal gear hub with automatic transmission.

[@Electroheads]

Our editor did a woopsy and though the geared hub was the motor! 😅

[@ProfSimonHolland]

@@Electroheadsi figured that.

[@humza890]

Interesting bike 🤔. I like the intergrated screen having google maps. The back sensor does sound very similar to Garmin radar light, which also detects how close cars are behind you. 2000 for this bike sounds alright. 4000, definately not. I suspect it may be a product that happens to 'always' be on sale.

[@vtmwatch2255]

See your point, but Not many have full carbon frame though.

[@philkitchen1924]

Been using a garmin rear radar on my cycle for years.best for open road not town

[@stockey]

They should sell the real time warning by itself, i would buy it.

[@amaanasif7819]

I hate company's tell fake range and I don't buy them thank for your review

[@vtmwatch2255]

Yup, but I think prototype related.... Shame this gets extrapolation because most people think they're looking at the final product...

[@vtmwatch2255]

Prototype has 18650 cells - final product will have 21700 cells. Shame Electroheads is not mentioning this while doing range testing.

[@adrianupnorth]

I like the design and that screen. How heavy is it?

[@Electroheads]

15kg for the single speed and 16kg for the three speed!

[@vtmwatch2255]

​@@ElectroheadsThe 3 speed geared hub (Lofandi) is 1,8Kg. According to Tezeus the bike is 15Kg with the hub included. (Are you adding an annotation for where you point to the hub while referring to the mid-drive motor? (At 3min57)

[@afshinfunk]

What is max. rider weight for Tezeus C8?

[@jonathanf.9395]

Yeah the classic bike bell is best. People immediately know what it is. Never fails.

[@jadedferret6727]

Yeah, they don't reach into their pocket and pull their cell phone out three times, before they realise i'm behind them!!

[@vtmwatch2255]

The ringtone can be set to classic bike-bell in the App. She forgot to mention that.

[@Ooklathemok3]

Reminds me of the cowboy ebike

[@badabing8884]

How is it a mid drive motor when it’s on the back wheel? That would make it a rear wheel hub motor.

[@Electroheads]

That’s the automatic gear hub you’re seeing 🙂

[@orthicon9]

@badabing8884 Yeah . . . at 03:48 she talks about the motor developed in-house, and the camera gives a closeup of the rear hub.Then there's "2.68 kg" and an arrow pointing right at the rear hub. Again, at 12:26, there's another closeup of the rear hub just when she says "... created their own mid-drive motor ...". On the Tezeus site, they show the location of the motor before the pedal crank arms are installed. I'm thinking now that @Electroheads made mistakes in post-production video editing.

[@Tezeusebike]

The rear wheel is equipped with an internal gear hub with automatic transmission. The mid-drive motor is actually built into the frame close to the crank.

[@jimmyfang9339]

Finally, Eilis has changed her trainers 😃

[@S_Paoli]

if someone is 6'8" and 220 pounds, does that make the range much shorter?(compared to someone who is 5'2" 105 pounds)

[@Alessandro---]

Following…

[@denverspin]

Yes

[@timscott3027]

I like the look but how is that touchscreen gonna handle the rain and cold? Maybe ok but i suspect it will cause problems. The tailight radar is a bit pointless. What are you supposed to do when you see a car approaching from behind? Jump out the way? You should be riding as safely as you can and someone rear ending you is one thing that is out of your control really. It maybe useful if your turning and didnt notice something i suppose 🤷 id have to ride it i guess. Not a great range really either, my single speed heavy fat bike gets more than this (it also has a bigger battery but i would have expected slightly better given the 3 speed and more efficient tires) that price seems steep too. Not one bfor me.

[@Alessandro---]

Completely agree on the rear radar. What is one supposed to do?

[@vtmwatch2255]

Prototype has 18650 cells - final product will have 21700 cells. Shame Electroheads is not mentioning this while doing range testing.

[@perjensen1962]

Would it in any way be possible to implement regen braking?

[@vtmwatch2255]

Useless on a bike. Techn. Effort/Results ratio too low.

[@denverspin]

There is a company called Stromer that has this option. Check them out.

[@maidbloke]

Great review thanks, but not the bike for me, too many flashy bits to go wrong

[@larshelmin]

Nice looking bike but... There is too much new unproven stuff on the bike (motor, radar, software etc) , they are setting themself up for quality problem later on.

[@Tezeusebike]

Thank you. We will continue to optimize this bike and deliver satisfactory products during the mass production stage. Stay tuned!

[@fastfreddy19641]

Perhaps a rear view camera instead of a warning radar?

[@Alessandro---]

My thoughts exactly, however seeing a screen in bright daylight might be more challenging than an audio or haptic warning. My thoughts as a non-rider are “ok, you’ve been warned that a Transit van is getting dangerously close: WHAT DO YOU DO NOW? Accelerate to increase distance? Get out of the way? Stop and wilt? Check your rider insurance?

[@Tezeusebike]

Hi there. We are currently optimizing the millimeter wave radar algorithm to reduce its false positive rate. Of course, if you find the alarm sound really annoying, you can turn off this feature through the touch screen.

[@tconnolly9820]

From a new start up that may not be around in a year or five years, there's way too much unique proprietary parts involved in this bike. Saying that, I wish them great success for the future. Anything goes wrong, your fecked. You're left with posh recycling. I'm currently seriously looking to buy my first workhorse e-bike and I'm going for a Bosch system regardless of brand. Although I have a top of my list I'm currently waiting to see if it's available in a 62cm frame. In ten years time, if a motor, sensor, battery or screen needs to be replaced then the parts should almost certainly still be available. There are hundreds of manufacturers building their bikes around the Bosch system. Essentially they are Bosch bikes regardless of the brand. Everything is standard and replaceable. As far as I can tell right now, it's the nearest you can get to Triggers broom for an e-bike. That was also the beauty of a good old manual push bike. In twenty years you could have replaced every single part and technically it's still the same bike. That ridiculous radar system fitted where it is means I couldn't put anything on a rear rack without blocking it. Too gimmicky anyway. I'd prefer two good quality motorcycle mirrors on the handlebars as I have on my current manual bicycle. I'm 2 metres tall and over 120kg before locks and luggage, another 20-30kg every ride. If Eilish is only getting 20 miles per charge, I'd be lucky to get 12. Not counting some steep hills. She'd be lucky to get 30 in summer. And for more than a Cube Kathmandu? Bigger battery, 85nm!

[@denverspin]

Yeah, Bosch is the best.

[@scottrichards3587]

Way too much eletronics to confuse rider and to fail

[@Tezeusebike]

Thank you for your criticism, we will optimize the existing functions to make this bike easier to operate.

[@BMFezekiel]

How tall is the rider?

[@longzero]

Everything about this bike is great except the price :P

[@vtmwatch2255]

Very early bird on Indiegogo is more than correct (some 60 bikes are left at EUR 1'990)

[@Tezeusebike]

Thank you very much for your recognition. We will face up to our shortcomings and continue to improve our product!

[@vtmwatch2255]

Where else do you get a full carbon frame @ EUR1999 (early bird) ? haven't seen one ...

[@djarcas]

£3200. Ouch. I bought a 1400 Ninja for less than that O.o

[@anonymousone6075]

Good review, Eilis, however, sounds all too good to be true, and defo not on the shopping list and no way at that price. Looks pretty, and has good features, but that flaky headlight is a killer and doesn't inspire at all.

[@vtmwatch2255]

You can have the light 'forced' on all the time, or select 'auto'.

[@zigzagtoes]

Mud guards (fenders) are an optional? Thats crazy when you consider what damage a stone can do when flicked up at 15+ mph, nevermind how wet/muddy you and pedestrains can get at those speeds from water spray.

[@WoodyWanderer]

I don’t get why lights etc are automatic. There is no need . It’s not hard to press a button to turn them on . They’re just trying to be over smart but when they do that things don’t work right . Also the mileage is always fake news it’s annoying they give you milage if you was on the lowest speed on flat service which is just unrealistic no one riding on slow and flat service in perfect weather conditions all time . How can it claim to do 63 miles and you’re saying it went to low after 15 miles ? That’s a massive difference to only get about 20 miles out of a claimed 63 miles bike But I do like how the google maps is built in and the weight and look is lovely . I’d buy this if the range was better . If they send me a freebie I’ll try it out ;)

[@vtmwatch2255]

E-heads tested a prototype with 18650 cells in the batt.pack. production model will have 21700 cells and deliver the indicated range. I wouldn't refer to this as fake info, I would rather call it an error of the reviewer failing to put out all the information to their viewers. The light can be auto or forced ON btw.

[@tomasr64]

City and road bikes really need a rear view mirror. The screen and back camera should be the rear view mirror. and the lights and controls? I'm not a fan of "smart" technology. got to have a manual overide. And only 20 mile range? Nah. Need at least 50mile range. I would have a loud horn. And for the price of the bike, they should have puncture proof tires. Finally, too expensive for what it is currently. Don't these designers get out and ride in traffic?

[@vtmwatch2255]

Where you get a full carbon ebike for EUR 1'990 ? (Early bird). Agree with the Puncture resistants, Schwalbe Marathon are only EUR 38. The light has an auto and 'forced' always on function.

[@robertmoore8334]

Interesting cycle to enter the ebike race, carbon fibre frame for weight reduction, not to sure about hidden cables other than looks as regards sevicing/repair would be a major pain, lack of suspension on UK roads mmmmm, battery range seems poor as the UK only gets a short few months of 20 degrees +, yes it's a prototype and rather expensive for a hub powered cycle, it requires a real life test in this country for 12 mths to see the perks of ownership over price also a build shakedown or reliability test... Is it a British designed machine or American? Where is it going to be manufactured? Do like this rear radar but the astute rider should always keep their witts about themselves and use your eyes n ears whilst cycling to prevent harm to yourself as yes as a simple commute is where your vulnerable mixed with other modes of transport. Will this make cyclists lazy in the long term? Like all the electronics fitted to cars these days, had the pleasure of a drive in a Q7 Audi quattro no pleasure in driving it as with all the sensors attached it drove itself with little input from the driver other than pushing a few controls sucking the life out of driving.... Keep up the great content as it provides a great insight to cycle design, manufacturing, technical development and the future of pedaling!!

It's from HongKong, and mid drive motor, the hub is just the 3 gears. She mistakenly points to the Hub while referring to the mid drive motor
