So before getting into my impressions of the build quality, performance and value of the Light Bee and Luna Cycle’s customer service, I’m going to post a bit of my background. I’ve ridden two wheeled motorized vehicles almost all of my life. I’ve raced motocross, TT and long haul desert events. Saddleback Park (RIP), Barstow to Vegas twice, Carlsbad, and Indian Dunes were just a few of the places my dirt bike days covered. Roger De Coster, Brad Lackey, Charlie Bower were my dirt bike heroes. I owned a Yamaha DT125, a Penton 125, a Bultaco Pursang (250) and a Maico 250 with leading link front forks. On road courses I campaigned a Honda RC51 1000cc vtwin. I belonged to Keigwins at the Track and was one of their original instructors. Laguna Seca, Buttonwillow, Thunderhill and Sears Point were our venues for both track days and training racetrack tactics.
As I aged I finally surmised I’d never contend in World Superbike and felt that my reaction times had gotten to the point where I may endanger my fellow racers so I stopped racing. Chasing a mid-level AMA racer and crashing in turn three at Laguna and then a helicopter ride to the Enloe Trauma Center in Chico after crashing at Thunderhill Raceway convinced me. I still did track time for a year and a half after that chopper ride though…..
And street riding, well I loved it in the early days, but after 28,000 miles of track riding/racing it just no longer appealed to me. So I got into mountain biking because I missed the ‘offroad life’ and bought a Specialized Hard Tail with Rock Shock forks. It was sure fun, but I missed the tinkering and fabricating a ‘real’ motorized two wheeled ride offered me. So I began looking into eMTBs and bought a Haibike Fullnine RC in 2016 from Motostrano in Redwood City. I’ve written a post about my experience with “Sofia” in another post on this site. You can read that here.
I wanted a ‘bit more’ in terms of speed and power so I started researching other ebikes. Not necessarily legal either…. I found two possible bikes, one made right here in San Francisco called The Bolt (which has now changed to Monday Motorbikes and they have moved to SoCal). At the time it was not really available for sale. I’m not sure if it is now since their website is not very clear about sales only preorders. And I could find very little non marketing material by real users of the bike. Plus the bike is really designed for street riding. And if I’m going to do that I would just use my now street legal RC51. But again, I’m not keen on street riding anymore. ESPECIALLY with all of the fuck heads who think texting is OK because they can multi task. Bullshit. Let’s play slap face texting. You text on your fucking phone while I slap your face and let’s see just how quick you can react to block my hand. Enough said.
The other bike that was VERY intriguing to me is the Neematic. A trellis frame, 50MPH top end and ‘seems’ well built. But at 8500 Euros and still vaporware I didn’t have much hope for the bike actually being produced in quantities that would actually hit US shores. And as of this blog post (June 2018) I still cannot determine if it’s being produced. And no actual user reviews of the unit…..bad. Not really much new marketing materials either…..suspicious.
I cannot recall how I happened upon the Sur Ron Firefly as it was called when I first happened upon it. But I sure as hell am glad I did!
The Meat and Potatoes
OK so like you I searched a LOT on Google about the Sur Ron. Lots of video reviews were done and the ones I especially appreciated are from Holmes Hobbies on YouTube. John (ahem he must get a LOT of shit about his name…LOL!) has such informative and useful information I highly respect his channel. The other resource I found helpful is by Sur-RonUSA and I’ve followed several of his recommendations on my own bike. I also researched Luna Cycle and had originally planned on flying down to LAX to visit their location. I grew up not far from LAX (Crenshaw) and know right where El Segundo is, but after reading TONS of information about the Sur Ron I opted to nix that idea. Why? Because reviews from actual users about both Luna and the Sur Ron convinced me to just pull the trigger. Eric and his crew at Luna seem like no nonsense, no bullshit fellas, the kind I like. As a matter of fact Eric reminds me of Paul Buff, a guy who doesn’t give a good hot shit about what established makers think of what he’s doing. He seem to only care about innovation and quality, much like Paul (may he rest in peace). And like Paul he has built his own company albeit a bit smaller and younger than PCB.
I can tell that Luna is a young and growing firm, having the same growing pains all young companies experience. But what instilled trust in me parting with 3500.00 USD plus tax and shipping was the level of response I received from his crew. And the other web posts that talked about his other products, those developed well before he became the sole US distributor for the Sur Ron. His video on the teardown of a Sur Ron was the final selling point. Having wrenched on Honda, Yamaha, Suzuki and Kawasaki motorcycles has shown me how brands stand above and beyond each other. Small things like bosses welded into frame points rather than loose connectors are the small things that show build quality. The video and the fella’s comments illustrated that. And when I received my own Sur Ron I confirmed the quality of the build. It’s a Honda level quality build and that’s saying a fucking ton.
Shortly after I made my purchase I noticed that Luna had discounted the pre orders by 200.00. I wrote to them to ask if I could get that price. They responded immediately that my account was credited 250.00 for any future purchases. Again, excellent customer service, well done and timely.
Luna shipped my bike via FedEx Freight which is different than the way I normally received FedEx packages. I was told from Luna that the driver would contact me via phone to confirm a date/time when my bike would be delivered. As I waited for the day my bike showed it was to be delivered, I received no call. And their website never showed “Out for Delivery.” So I called FedEx and was transferred from the number I normally call to their Freight division. I was pissed when I was told that the bike which showed it was to be delivered on a Friday would not be delivered until the following Wednesday. As a young man I had the patience of a teenage male’s stiff dick and as a more elderly person now I have a little more patience….of a 28 year old hard on! LOL!!! Just be aware that when you get notification from Luna that FedEx has picked up your bike, CALL FedEx Freight. Their number is 866-393-4585, don’t call their normal package delivery number. Don’t just trust their website, call!
My Sur Ron was well packaged and included the installed Pedal Kit which I had ordered. As a matter of fact had Luna not offered the pedal kit I would not have purchased the unit. In reality the pedals don’t really do much to propel the bike forward. And of all the elements on the bike the rotating spline on the pedal kit is the weakest link. It is not well machine and has a significant amount of play while rotating. Why get the pedal kit at all? I’m not going to answer that for you, but it should be obvious why you’d want them…..enough said.
One of the YouTube videos I watched shows the guy cutting the shipping straps, but I found that they make handy tie downs so instead of cutting you may want to just untie the ends and release the buckles.
I suggest that you immediately remove the battery and begin the charging process. My Sur Ron arrived with an 83% charge in the battery.
I believe this is v2 of the charger. In Homes Hobbies video he mentions that Sur Ron had revised the charger from the one he received which I don’t believe had the fins or fan. This charger remains dead cold as it charges, as does the battery.
The Pedal Kit includes the pegs too, so not to worry. A simple tool kit is included which takes care of mounting the front wheel.
Luna’s Mountain bike pedals are nice large flat and studded pedals. One of the issues I found is on the left side of the pedal kit the threads are not reverse threaded meaning counter clockwise tightening. Since the pedals rotate counterclockwise on that side it can loosen the 14mm nut. I found that putting Blue Loctite thread locker on the nut/bolt thread helps prevent this. Also the two hex head bolts on the right side of the pedal kit must be tightened to get any friction on the pedals. Mine shipped loosely fastened.
The user guide refers to a ‘fuse box’ located in front of the ‘air switch’ and an extra fuse. I could not locate a fuse box or an extra fuse. I believe the air switch is a breaker switch, much like you have in a modern house.
In this shot the breaker switch is the red switch just below the ignition/USB plug. I’m not sure what the white connector is with the black electrical tape’s function is for the Sur Ron. (Editor’s note: that is the fusebox)
The suspension is damn impressive. Compression and rebound on both front and rear. I converted my RC51 to full Ohlins forks and shock just to get those features!
Compression for the front really works. Just adjust a click at a time.
Rebound on the same fork leg as the compression adjustments dial is located at the bottom of the right fork.
Rear shock’s compression damping is on the top of the remote reservoir. Rebound is located on the bottom. I’ve adjusted the spring preload. It comes fully extended, so adjust to your weight/riding preference.
During my first rides I had an issue where my Sur Ron would either cut off engine response to the throttle or not respond at all to the throttle when leaving my garage. The level of battery power varied anywhere between 100% to 70%. The lights and the display stayed on, just the response to power died. After writing to Luna it was suggested that it ‘may’ be the brake safety sensors. After contacting John Holmes at Holmes Hobbies he instructed me how to remove the brake cut off sensors. I removed the threaded collars that are just below the brake lines on each of the hand levers. I noticed that on the front brake (right) the very small set screw was backed very far out. I’m assuming that may have caused my no throttle issue. I have no idea how those sensors work, as they don’t seem to be pressure sensitive, but rather magnetic. In any event after removing the brake sensors I have not had any issues with the throttle not responding.
I replaced the sleeve bolts and filled them with Instamorph (BEST shit EVER!!!) to ensure moisture doesn’t get into the master cylinder levers.
These are the brake sensors in the levers. I could not locate any moving parts which may indicate they are magnetic sensors.
I found that both the rear and front brake lines were about 5 inches too long. So I shortened them to what I feel is the proper length so they don’t catch on brush or branches. Like mountain bike hydraulic disc brakes the Sur Ron uses Mineral Oil for hydraulic fluid. I have tons of that from changing my ebike brakes. Just use a sharp pair of cutters to cut the lines and buy some brake Olive and connector pieces. Bleed the brakes and you’re all set!
Removing the brake sensors and trimming the brake lines made Christy’s front end very tidy!
I also took the advice from one of the site’s I’ve listed to increase the height of the stem by simply reversing it upside-down. Doing so adds about an inch of reach at no cost. Very slick! The Quad Lock bracket simply holds my cell phone when I ride.
I like riding in the rain and the resulting mud. OK so I never outgrew the toddler phase of my life, so what?! LOL. But after racing off-road I know firsthand the toll packed mud can take on suspension or cooling fins. It’s never pretty. So I’ve installed a fender on the front of Christy and am installing a rear off-road shock guard to keep mud off of the shock body, linkage and spring.
Front Fender by Mud Hugger. Rear is fabricated by me. I simply took a 5.5 inch piece of 90 degree aluminum and cut/bolted it to the existing bosses on Christy’s swing arm. Just buy an addition 5mm x 12mm long bolt for the right side boss which is empty. I attached a Honda mud flap to finish the job.
I will be riding solitary most of the time. I don’t know others who own bikes like this so I feel it’s important to carry some basic tools with me along with a first aid kit. I use to tell students at the track, “Hey I know it’s fucking hot today. It’s fine to not wear your back protector. Just wear it when you know you’re going to crash!” The Sur Ron uses fasteners that are basically mountain bike nuts and bolts so I’ve lashed a multi tool pouch with a MTB multi tool to the right side seat frame.
And I plan to go on extended rides, sometimes at night. So I want to carry snacks or extra layers of clothing. So I simply bought an off road tank bag by Wolfman. It’s perfect for my needs and stays damn secure on Christy’s ‘tank.’ And yes that’s a water bottle on the right side of the frame. I hate wearing a backpack so I installed some removable boss fittings onto the frame to attach a water bottle cage. Does it stay secure? Yes it does!
What Luna and Sur Ron have here is what I consider to be an absolute winner. The build quality of the bike is incredible. I have no idea how either of those companies make a profit off of these bikes. The margins must be very slim. The fun factor is incredible and I’m sure there will be loads of performance upgrades.
In terms of performance upgrades I’m a real bitch about tire pressure, brake performance and suspension over horsepower. I had read somewhere that a user was going to change the stock Sur Ron brakes to Magura MT5s. I installed those on my eMTB, but I find the stock Sur Ron’s are great and don’t plan on any brake conversion. Great feel and modulation on the stock units.
Sure like anyone else I like ‘more power’ but after racing I KNOW that it’s what you can USE and for me races are won or lost entering and exiting turns. Late braking and getting on the pipe coming out of the corner is where it’s at. Additional horsepower is great, but at the expense of greatly reduced battery range would be an issue for me. I’ll keep Christy for what I think are for the rest of my days. And after that my daughter wants Christy! She’s pissed that I let her ride it on Father’s Day. Now she’s figuring out how to budget her funds to get her own…..or when her old man will die and leave her the bike and all of my damn tools!
I had purchased a Thule Easy Fold bike rack prior to purchasing my Sur Ron for the two ebikes we own. Both are Haibikes one a Full Nine and the other a Trekking. So I wanted to find out if I could use the Easy Fold to transport the Sur Ron and guess what? It can which means I don’t need to have or rent a truck to take it to off road parks or trails! SCORE!
Update: June 27 2018
Today I installed the Luna Cycle 60t stainless steel sprocket. My desire for more lower end torque over top end prompted me to purchase one of Eric’s units. Went on easy as can be. My only concern is that the included chain extension takes the chain adjusting screws to almost the end of their reach. Not a big deal, but I will probably remove a link to keep the rear axle in the middle of the adjustment range. The added torque down low changes the personality of the Sur Ron more to my personal taste. Exiting a corner and the ability to climb steep hills has always been good, but now it’s great!
Tonight I wanted to see just how much the 60t sprocket reduced my top speed. (like I need ANY excuse to ride Christy!) Luna states that it will max out the top end at 28MPH. Another user stated he obtained a top speed of 32 MPH. Tonight I got 36 MPH measured via a GPS app on flat ground. The hill climbing with the larger sprocket is incredible especially for a bike this small and this light. For what I use my bike for anything over 30 MPH is plenty. My top track speed on my RC51 was 168 MPH so if I want top end I’ll ride that bike! LOL
I’m not sure what the angle degree it is to get up to this spot, but it’s easily over 30 degrees. No question if the Sur Ron would climb this hill, not even a slight hesitation. Remarkable.
I am pleased with the modifications I’ve done to my Sur Ron. I added a First Aid kit to the front. Why? If you’ve never crashed while riding alone in a remote area then you have no experience in being injured and alone. Enough said. I continue to be impressed with the Sur Ron and plan to mount the 60t rear sprocket I purchased from Luna next week. Don’t need top end, need more torque…. Stay tuned. The fenders work very well to keep mud from being flung onto the controller and the rear linkage and shock body. One definite improvement I’d like to see either Sur Ron or a third party make happen…a better seat! I tend to ride an average of 20-25 miles at a time and man my ass hurts! I’m not a big fella nor do I have a big ass, but the seat makes my ass hurt. Even when I wear bike shorts with padding! And if you think it’s because I have a peddle kit, think again grasshopper! LOL
