This is the highest power Luna Bike ever offered, and features a Luna Exclusive - a BBSHD with our own custom "Ludicrous" Edition 50 amp controller, the most power to ever be offering in a BBSHD drive. It is being offered at an special introductory price for early adopters.  

We are offering it for people who know what they are doing and will be responsible with this kind of power (know what gear to ride in etc.)

We prefer to sale this bike to former customers only. If you are a new customer you may need to convince us that this is the bike you want. This is for people who have owned the stock BBSHD and want more. 

It is not legal to ride this bike in Ludicrous Mode on public streets or trails. We sale this bike for private property (hunters etc) and race track riders.


Big announcements:

This bike features a very special made in the USA battery which is the ultimate in high performance and reliability.

The pack uses the latest technology in construction and materials to make it water proof and collision proof. 

Read independent  review on this 50amp bike here.

We have spent months secretly testing the BBSHD with this controller (multiple test units) and have decided to only offer this special Luna controller on our complete bikes because of special needs this controller needs in terms of battery and programming. 

We are only offering the Ludicrous Upgrade to customers who will use the bike off road and private property only, and only to loyal former customers who are familiar already with the power of this type of mid drive.

Your bike will retain all the gentile characteristics of the normal BBSHD along with pedal assist  program setting etc. We have specially programmed this unit to handle the extra power while still having a very smooth operation.

Your bike will be identical to a regular BBSHD, except the controller is different, but the bike will use the same firmware and the Luna Hot Rod Program setting specially tweaked for this bike.  The only difference is your bike will have 50 amps for serious power instead of 30 amps.

Top speed will stay about the same (just a few mph faster) but you will have serious high power torque that a stock BBSHD does not have.

Choose from 9 levels of power assist, even when applying throttle the power will come on smooth so as not to rip apart your drive line components.

  • 52v 17..5ah Panasoinc GA High Performance Battery Pack  made for this pack

  1. Freakin awesome for a production bike

    Posted by Unknown on Jul 17th 2017

    I've had mine for about 6 months now and have done about 200 miles of seriously steep trail riding. Stuff so steep it's scary to go back down. I installed a 30T Mighty Mini chain ring and edited the rear cassette to correct the chain line. I also upgraded to the Luna Lander fork and installed a Thudbuster LT. This really smooths out the bumps. I was skeptical about fat tires at first, but now I would never go back. The traction I get is amazing and deep sand barely slows it down. I get about 30mph top speed on level ground. I did have an issue with the battery when it was new, but Luna took care of it and it has been perfect since.

  2. Almost motor power without noise

    Took her down to San Rafael swell UT and she loved it. Great bike - 20-30mi range - will change (to wider) bars and dropper post but those are minor changes. Thanks Luna!!!

  3. pretty good product,,, great value

    Took 10 weeks to get a street legal version. One stripped pedal crank and defective wheel speed sensor right out of the box. Fixed the first, waiting on replacement for second. First ebike and would have appreciated some basic manuals on what to expect . Thats the bad news. Exceeds expectations for performance and overall quality. Have had many compliments on value and performance. Have ridden through sand and over some pretty rugged rocky conditions. Hopefully with the new speed sensor and more experimenting with suspension adjustments i can begin to fully appreciate the whole package more.
