General Description

Luna Cycles knew fat tire bikes were going to be a big thing before they actually became one. Starting with Luna Cycle’s first custom made frame, we always had a vision of building a beautiful Fat Ebike in mind.
With KHS’s 4 Season 500 Fat Tire Bike you get one of our most affordable fat bikes. It is good enough if you do not plan to do serious trail riding, and looks just as awesome as many of our higher end fat bikes at a very descent price. 

This Fat Tire Bike with a BBSHD  is a powerful bike with a 13.5ah battery in the triangle is all the fat bike that most people need.

Panasonic 52v GA 13.5ah Battery


The battery is the most vital of any ebike.  We use the best 18650 cells available (the Panasonic GA) which offer both amazing energy density and high performance.  We make our packs with quality BMS, cases etc...cutting edge technology.  You can have confidence that when this bike is outfitted with a Luna Cycle battery you are getting the ultimate in reliable, safe, performance at an affordable price.  Our competitors sale a 48v of this pack for over $1000!  Look here for more Info on this pack.
Research ebike battery packs and you will see the Panasonic GA Shark is the best battery available today.
We use a quick change pack which allows you to extend your range by quickly swapping the pack. You can swap packs in about a minute.

Mounted Inside the Triangle - Perfect

Also this ebike has the battery mounted inside  the frame in the triangle where it belongs for the ultimate in balance and good looks. The battery in the triangle is the best solution for any ebike.  We don’t do the easy thing like other ebike companies and weld the battery case to a rear rack which is the worst place for the battery making your bike back heavy. (especially with a rear hub motor)
Also out packs are quick release for the ultimate in convenience. Double your range by buying a 2nd battery at a discount when you buy this bike.

Top of the Line Mid Drive Motor Set Up

mid drive.jpg

Luna is  offering this ebike in a BBSHD format....these drives are the most reliable and powerful drive systems  available on the market your  own research to back that up.  And much more expensive for us to buy than a cheap hub motor.  But we are selling them for less money than cheap hub motor bikes typically sell for.
These mid drives are completely silent, efficient, and fun to ride. They have  quality color display and both throttle and pedal assist.
Luna Cycles offers no hub motor bikes....but only mid drive bikes because we believe in offering only the cutting edge.  
You will not find this quality with any production bike at this price point anywhere.
Or you can save even more money by converting your own bike and buying one of our kits here. (read about the advantage of mid drive here)
LunaCycle realizes that not everyone is into building and is offering a turn key Fat Bike with a BBSHD drive (read about our most popular drive here). This is still another price break through for a quality bike with quality components.  We want to make awesome ebikes affordable for everyone.
Although we specialize in build your own kits, Luna can build your bike for you at a fraction of the price a store bought bike would cost you for this amazing performance.

Color Display / Control Center

color display.jpg

Like all the Luna Bikes  this bike comes with the DPC-14 a  full color display which gives you valuable insight such as battery life, speed, and miles travelled.  It automatically changes to dark mode when the sun goes down so you ride in “stealth” mode.  There are very few production  bikes under $5,000 with this quality of display


21 Piece Luna Toolkit


Because we feel every rider should have the capacity to wrench, we are including a free luna kit which is all tools we either made or hand selected to be perfect companion to one of our mid drive bikes.

This will help you because our high performance mid drive bikes will need  occasional adjustments, This kit along with our video guides will give you the tools you need.


Frame Sizing

Please don't stress about about frame size the way you do when you buy a pedal bike….it’s not as important.

With electric bikes it is not important to get the right frame sizing, since you are not reliant on efficient human power for propulsion, you won’t notice much of a difference since the motor is doing the lion's share of the work.. We actually recommend going with  a smaller size with an ebike than you would get for a pedal bike, because smaller sizes are better for keeping the weight and center of balance low, and are easier to get on and off of (since ebikes are heavier they are more awkward to tilt to swing your leg over)... You can always raise your seat or raise your handlebars….but keep the center of balance low and get a smaller sized bike if you can.

Note that many of our  full suspension bikes only come in large and xlarge...this is because it is the only sizes that fit our battery packs.

Warranty Options

We are an ecommerce company and ship this bike to you wherever you are at. We charge minimal markup because we do not offer face to face support.  Most of our sales are to enthusiasts and to builders who know what they want and don’t need a lot of assistance from their dealer. You can use our forums and knowledgebase to find the answer to almost any support question you have.

If you expect your bicycle to be flawless and never need adjustment or maintenance, we recommend that you buy your ebike from a local brick and mortar ebike store if you have one near you, especially if you want person to person support when it comes to adjustments and maintenance of your ebike.  We do not offer this level of support.

Bikes are large and expensive to ship, and once you ride it it is used, and we do not offer any returns on your bike unless it is dead on arrival.

For 30  days after you get the bike we will replace any parts that are defective.
These are just bicycles and are easy to maintain and to work on…. And we really encourage you to learn basic bicycle maintenance or get a relationship with a local bike shop.

The Drive system and battery we will cover for 90 days for part replacement.  

Extended warranties are available for 6 months and 1 year and 2 year  for an added cost. Warranty covers any parts that are defective we will send to you with instructions how to install.

Since our drive systems are modular every repair is easy with the right part in hand.

That being said this a high quality bike with a high quality component system and should be as solid as any ebike. However you will be required to do routine adjustments and maintenance on your own.

I would've written this review much earlier, but honestly, I spend every possible minute riding this bike. Incredibly fast, goes over any kind of terrain. I've gotten so many compliments on the bike. As far as Luna goes... Seb and some other guys spent a lot of time with me, customizing the bike so it was perfect. i could really tell that these guys are hard-core bike enthusiasts. I'd highly recommend the 24 ah pack - took a pretty hard core 3 hour ride yesterday and only used about 25% of my juice. Luna customer for life...

Fantastic Bike!

This bike is solid! I'm very happy that I chose to purchase from Luna Cycles, and just as happy I chose the KHS 500 with the Ludicrous upgrade as my first ebike. It was very well packed and arrived in very good condition. I charged it overnight and half a dozen friends, family, and I began learning how to use it and had a blast! We had so much fun that several are now looking at getting conversion kits and bikes from Luna. If you're looking to get a great bike or convert your own you can't go wrong with Luna or the KHS 500 fatty.
