Cleanest Ebike Ever 

Luna is proud to offer the cleanest production ebike ever for under $2000. If you know of a bike that is cleaner at a comparable price please let us know and we will do public challenge. This is not the fast and powerful ebike Luna is well known for selling. in fact this is the lowest power bike we have ever offered. This is one clean ebike. 

This is why we think the Fixed is probably the cleanest: 

  • Battery built into the downtube frame and based on high capacity Panasonic GA cells
  • Carbon Gates Belt Drive group set: 22T rear and 55T front
  • Only 39 pounds 
  • Fixie minimalist frame style
  • 700x35C tires (Kenda tires, threaded) 50-85PSI, 21.4mm outer rim width
  • All wires and cables run through the frame 
  • Torque sensing mid drive
  • Shimano NEXUS 3 speed SG-3D55 Internal gear hub with silent clutch 
  • Elegant black on black color scheme
  • Silent motor that is totally stealth
  • Legal in all 50 states
  • Easy on the pocketbook as it is on the eyes
  • No oily chain mess on your fingers or carpet, carry this bike up your stairs without a problem

For those that thought Luna bikes were too fast, too heavy, too fat, too big of a battery, too expensive, we got you the Luna Fixed.

This is our answer. The Fixed is our hipster electric bike that is so stealth it will really be hard for anyone to tell your riding an ebike.

This is not a high power bike, this is for all the people who want an extra 500 watts of power and keep their bike with bike like qualities. It has no throttle, torque sensor only. 

That being said this bike has 3 speeds, in gear #3 you should be able to reach 27mph +. The power does not shut off at a certain speed in the highest PAS level so if you are already pretty fast on your road or fixie bike you will be scary fast on this bike. 

Space "Tube"  Battery

36v 7ah 260 Watt Hours Panasonic GA Cells

36v 7ah 250 watt hours Panasonic GA cells.

This bike does not have a giant battery, instead it has a very small Panasonic 18650 battery built into the alloy downtube, and the battery is in its own alloy tube (battery case is pictured above).  This is the ultimate in stealth and also safety since the battery is fully enclosed in double tubed aluminum.  Because this is a very efficient lower power mid drive (400w) with road bike tires and a torque sensor (no throttle), you will be able to go many miles on a single charge despite the batteries small size.  We estimate around 20 miles per charge although your milage may vary somewhat.

Ultra efficient road bike with Gates CDX belt drive group set and Shimano internal gear 3 speed built into rear hub for the ultimate in smoothness and efficiency.  Add a torque sensing mid drive motor and a completely stealth built into the bike battery to the mix, and you have probably the cleanest production ebikes ever made for under $5000 and we have decided to sell it at a fraction of that price.

Gates Carbon CDX Group Set


This bike features the very latest in belt drive technology using the patented Gates CDX group set with center spline which holds the belt on tightly with no slippage. This clean set up practically guarantees never replacing the belt for the life time of the bike.

  • 22T Gates CDX rear sprocket, Surefit 3-Lobe
  • 55T Gates CDX front sprocket 104 BCD
  • 120T Gates CDX Belt
  • The belt is rated for 20,000 miles 
  • No more worry about chain grease
  • No more worry about caring for your chain
  • No more worry about rusty chains
  • Slightly more efficient than a chain
  • Stealthy quiet when compared to a chain
  • Smooth as silk

Really on a road bike with the super slick internal gear 3 speed Shimano nexus with silent clutch, this system is as good as it gets.

Exceptional Value

The Luna fix is $1750. You will not see a bike close to this quality for this price.  How does Luna keep their prices so low? By selling direct to you with no dealers in between.  We want to offer never seen before bikes at ridiculously good value prices (different than just being cheap).

Totally Quiet and Stealth

Because the Panasonic GA  battery pack is built into the downtube and the motor is built into the bottom bracket, you can barely tell this bike is an ebike, this is the stealthiest bike we have ever built.  This bike can only be detected to be an electric bike if you look at it from the left side and see the over-sized bottom bracket, and that would take a second glance to see that.  No hub motor give away, no hanging mid drive. This is the most stealth ebike on the market without buying an expensive Grueber assist (like the professional road bike racers use to mechanically dope and win races).


With its belt drive, silent clutch freewheel, internal gear hub and small road bike tires, this bike is quieter than 90% of pedal bicycle. You will not hear annoying clanking and clicking even when you switch gears. The motor noise is barely hearable, road friction and chain clatter are all gone.

Internal Gear Hub (IGH)

Mid motor and an internal gear hub are a really sweet solution for an electric bike.  This Shimano 3 speed internal gear hub is the latest version with a silent clutch to help reduce the clicking noise of a bike freewheel.  It is small and lightweight, and is known for taking more power than its more expensive 8 speed counterparts.  We believe that 3 speeds is enough for a road electric bike, in fact 3 speeds is the sweet spot in an electric assisted bike.  Shifts are done silently and smoothly and quiet, no derailleurs, no chain to upkeep and grease, no annoying chain line problems.  The belt drive and IGH fixes many of the annoying problems of a multiple speed derailleur bike.

Read our article on IGH’s and why the 3 speed is our favorite.

Lightweight and Simple to Ride

Our goal of the bike is to capture all the simplicity and fun of riding of a fixie in an electric bike.  This bike only weighs 39 pounds - which makes it one of the lightest production ebikes on the market and still is a sweet luxury to ride, even without the motor this bike would still be a joy to ride.  Add the motor and battery, and you get an extra 400 watt bonus which should triple the output most riders can put out on their own.

Internal gear hub means you have 3 speeds without the hassle of gear clutter, and when you want to change speeds you change them no matter if your stopped or moving.

Torque sensing pedal assist means no extra wiring or complications of throttle, when you want to go faster you just pedal faster. You have 3 levels of pedal assist which you can easily change on the display which will give you more or less power based on how hard you are pedalling.

This ride is street legal in all 50 states and at these lower power levels (under 400 watts) you will have a very dependable system that should last for years to come.

This is a great bike!!

1 week in and very happy with this bike. It is amazing value for money and the bike does everything the manufacturer promises. The delivery time was incredibly fast and the bike arrived in great shape, was easy to assemble and required minimal adjustments (a little fiddling with the gears but otherwise great)!
The bike is incredibly nimble riding around town and is perfect for my 5 mile commute each way to work. I adjusted the peddle assist to 5 settings rather than the manufacturer setting of 3 and like the additional choice. I spend most of my commute in level 3, with the occasional increase to 4 on hills on the way into work and 5 on the way home (which can be incredibly fast!!).
I read a lot of blogs before the purchase and agree with most comments that the trade-offs between price and what the bike offers strikes a great balance. It would be great to have 5 speed gears (with a higher top gear) but I have been able to push to 27 mph which is pretty great. I find the brakes to be responsive (not as powerful as the hydraulic disks on my Spot Brand but good enough to stop fast in emergencies).
The one thing I might rethink is on the size - I should probably have bought a medium but went for the small as I read that it makes sense to go for a smaller size. So while the bike feels just a little small for me, the upside is I ride lower to the ground and it is incredibly maneuverable and nimble, which is not a bad trade-off when the peddle assist is doing a lot of the work.
I would have no hesitation recommending this bike to others - it is heaps of fun to ride and I am going to have trouble going back to my regular bike. I am sold!!

Making commuting fun again

Bike is an absolute dream to ride! The first couple pedals when you feel that motor kick in... its quite something. This was the first ebike I've been on but the torque sensor is amazing.

I live in central New Mexico and typically I wouldn't think of biking to work in the summer. With the assist you can get around without sweating through everything you own. The assist also allows you to contend with traffic better. Being able to take off at a traffic light helps you get out of the way of cars and just makes the whole experience feel safer.

The bike does come with a couple caveats you should be aware of: there is almost no documentation on the bike; it seems to be shipped as is from the factory in china. Fortunately, there is fairly active crew of 'Fixed' riders on Reddit (r/LunaOwners) that have been troubleshooting problems.
Be prepared to try to take as much tension out of the belt when you get it as it comes pretty tight and seems to be causing problems for others. Even with the belt tensioner entirely removed the belt on this thing is still on the tight side of where it should be. I'm not belt drive expert but it seems this bike should have come with a slightly bigger belt.
The battery range is certainly a little disappointing, but that shouldn't be a big surprise.
Runs a bit bigger than I was expecting, I'm 5'8" and the medium is just on the edge of too big.
