Written Review

The Zeitgeist City is a premium, all-Carbon fiber speed pedelec. It’s an electric bike that can high 28 mph and only weighs ~43 lbs which is impressive given the 500 watt hub motor and 48 volt battery pack. At one point, I believe this model was being called the Zeitgeist by Karma Bikes but the company may have adjusted due to confusion with the Fisker Karma electric car… My experience testing this ebike was great because I could tell they put a lot of thought into the design (which is comfortable and well balanced). I especially liked the removable magnetic LCD display and optional wireless button pad because the bike still operates without it if you want to go for a minimal look and reduced weight but using it makes navigating the nine levels of assist possible without taking your left hand off the grip. The grips are also a highlight for me with a locking ergonomic design and unique Aluminum bar ends for changing hand position. The Zeitgeist City is a cross between a city and road bike from my point of view, the addition of rear rack bosses is great for those who plan to commute and want to add a set of panniers or trunk bag.

When you look at this thing from the side it almost looks like a normal bicycle, in large part due to the two-tone paint job, the battery disappears and the white glossy highlights create a safe visual footprint. It’s definitely an active geometry and there’s no suspension but to me Carbon fiber rides nicely and absorbs more road vibration than Aluminum and is lighter than steel. It comes with large hydraulic disc brakes and e-bike specific levers that cut power to the motor… my only complaint is the higher price point. I’m not sure I’ve seen anything out there with similar specs, high speed, low weight and cool appearance so the price is founded but a bit excessive. The other limitation is that it only comes in one sort of medium frame size with a relatively straight top tube that can make mounting and standing over difficult for shorter riders. This thing would be a blast to own for road cycling with friends in hilly or mountainous regions and could make an excellent commuter, rather than going with thin narrow tires they upgraded to ebike specific Schwalbe Energizer Plus that are puncture resistant and a bit more forgiving due to larger 1.75″ radius which makes a lot of sense to me.


  • One of the only electric bikes I’ve tested that is almost completely made from carbon fiber! That includes the seat post, stem, handlebar and of course the fork
  • Considering the large 48 volt battery pack and 500 watt motor this bike is pretty light weight and handles very well because that weight is kept low and relatively centered across the frame
  • I really like the custom stem with integrated LCD display panel… that’s removable! I’m seeing more custom panels these days but very few let you take them out (to prevent tampering and exposure to the weather), well thought out design
  • Pedal assist is very responsive, I was told it’s torque based but it responded almost like a cadence sensor for me (not requiring as much force when pedaling) maybe it’s just dialed in to be very sensitive
  • Class 3 speed pedelec capable of hitting 28 mph fairly easily due to the light weight efficient design and larger 700c wheelset, it’s satisfying to accelerate or cruise at top speed
  • Quality tires with reflective sidewalls for safety and integrated puncture protection, the quick release front wheel makes changing flats or moving the bike in vehicles easier
  • Large, powerful hydraulic disc brakes with ebike specific extended levers that cut power to the motor instantly when activated, they worked well and felt sturdy at high speed
  • Zeitgeist offers optional Thule rack accessories but the City frame also features threaded eyelets on the seat stays for adding a more traditional rack that could work with a trunk bag and panniers for commuting, I like that the bike also comes with a kickstand (which is removable if you want)
  • Almost all of the wires are run directly through the frame on this bike and it looks great, they are exposed at the bottom bracket but this might make tuneups and maintenance easier, there’s a convenient disconnect point near the motor for rear wheel maintenance
  • Quality drivetrain (shifters and derailleurs), Shimano Deore XT components are light weight, designed to stay tuned and offer high performance


  • Currently the Zeitgeist City is only available in one frame size with high-step design so this might not be a fit for super tall or petite riders
  • Extremely expensive at nearly $8k but it does perform well, look great and is likely a very exclusive ebike, there are regular pedal powered bikes that cost this much which are also custom carbon fiber frames so I get it
  • No drop bar option for those who prefer an even more aggressive body position but it did ride more like a road bike, I like the ergonomic locking grips and bar ends for changing hand position
  • No integrated lights on this bike, considering the frame is custom designed it would have been cool to see an LED based lighting system running off the main battery vs. having to add your own
  • The wireless button pad is easy to reach (to adjust assist level or cycle through display modes) but requires its own batteries vs. being run off the main pack with one tiny extra wire, I was told the battery should last two years and is easy to change, you can completely remove the buttons if you want and use a single button below the stem as a backup which is cool
  • The included pedals are very basic, not as wide or rigid as some of the magnesium platforms I’ve seen from Wellgo but this choice might have been made because many people have their own or use clip in options at higher speed

Hi Cameron, I've been testing the site without ratings because I feel that a single number/stars isn't deep enough to communicate the variety and year differences between bikes. I'm focusing on deeper videos with more pros/cons instead :)

Stu Berman

Hi Court, the more that I look at all the e-bikes out there, the more interested I am in the Zeitgeist, but the one size fits all approach does concern me. I'm 5'8" and I think you said elsewhere that you're 5'9". How well do you think the Zeitgeist fit you, especially as compared to other e-bikes?

Court Rye
9 months ago

Hi Stu! It's difficult to remember exactly as the review was done quite a while back and I test so many bikes. As average sized people I feel like both of us would fit this bike just fine, there are little adjustments you can make with the seat post height and handlebar but if you start replacing stuff it could interfere with the electronics or weight (the included Carbon fiber stem and bars are much lighter). If you like the bike I think you could make it work... it's designed to fit the highest number of people, the peak of the bell curve and I feel like you're right there.

Hi Court, Thanks for a great site and awesome reviews. Did you notice if it looked possible to fit fenders to the Zeitgeist?

Court Rye
4 months ago

Hi Fencible! I bet it's possible but may require some custom work... and even then, finding parts that match and can be attached without too much rattling while still being solid (especially important at high speeds) could be difficult and expensive. I looked closely at some of the pictures and didn't see support arm bosses or the standard holes often used for bolts and mounting tabs (perhaps I was missing them). Hope this helps guide you, I think the short answer is no, it's not really optimized for adding fenders but you could use a seat post mounted rear fender like this or a carry rack to keep water off your back since it does appear to have seat stay bosses.

Great review. Nice looking bike ... But I really don't see how this thing
is priced at $8K. They will sell a ton at $4K, but at $8K, it's only gonna
be a store display.

+William Lam It's not gonna be the final price. Its better to price higher
and test price points. 4k is too low though.

7999$. This is more expensive than a car. I would ride an electric bike
with 45 km/h limit. But these bikes are starting at 4500€.

+Rob Schmitt China will clone these soon enough,I predict we'll see
versions of this style next year for under $2000.

11 months ago

+Rob Schmitt you're spot on. Our average street price in the US will settle
at $5k-$6.5k for the limited edition selling on ToMo. I think the there are
two electric bike markets in the US- the value and the designer. This might
fit the latter.

11 months ago

+Rob Schmitt Yeah, it's one of the pricier options I've seen... I've
reviewed a few other speed pedelecs (with a few being cheaper) back at the
site: http://electricbikereview.com/tag/speed/ the new 2016 Turbo is ~$3k
and goes ~26 mph (~42km/h)

The cross current from juiced riders has similar specs with the same
battery for $1500. You could buy 5 of them plus a spare battery for 8K. The
owner of this company certainly ain't thinking about the masses.

I'm surprised the electric firms aren't making more recumbents. Logic would
dictate this is the real market, older riders who need assistance to ride
like a young man and they are going recumbent. Ya, I know about Bionx and
it appears to be a good system.

11 months ago

+William Wonder Hi William, here's one amazing recumbent with full
suspension and regeneration! Very cool in my opinion:
maybe we'll see others like it in the future made with Carbon fiber like
the Zeitgeist City :D

+Jappe Kapanen Get this bike at a limited sale on #Touchofmodern

11 months ago

+Jappe Kapanen I would think so, SR Suntour makes a few minimal suspension
forks like this... they aren't as light as a carbon fork but they are still
slim and you get 100 mm or so. I'm reviewing one other Zeitgeist ebike and
it does have a suspension fork (but the frame is Aluminum vs Carbon).

I like how the battery is integrated but that does not justify the price.
We gotta teach those companies that we wont just pay any amount of money.
If anybody's interested in a similar bike like this, just look around,
there are lower priced options available.

11 months ago

+nerdexproject Good points, I agree :)

11 months ago

Yeah that might be true but unlike BMW, Zeitgeist isn't a coveted brand.
And if they want to get there, being expensive isn't the only answer. They
must offer desirable features and first and foremost they need at least
lights imo. At least they're doing the design right.

11 months ago

+nerdexproject I think they realize that it's expensive but that's part of
the appeal... just like a Coach handbag or a BMW. There are many other
affordable ebikes out there, having something different like this just
signals mass appeal to me and the desire for some consumers to go for style
and quality at a higher price. It costs a lot to create a custom frame like
this with electronics and display to match.

One of the best looking e-bikes out there. I really like the integrated
flush computer in the stem. It's just too bad the price point is way out
there in Neverland. Great review as always!

Great bike, but you have to make a lot, a ton of money to justify something
that price, mortals can only watch your video, good one as usual, thanks.

11 months ago

If you use it everyday it isn't expensive in the end. I bought my bike 20
years ago. I've changed the brakes, gears and saddle only once, that's all
the repair needed. I've never paid gas or taxes and parking is cheaper or
free. The only problem is that winter commute is hard or sometimes
impossible, but on the plus side my body is aparently in very good shape
and never been in a gym
