Test runs are done. It’s time to powder coat the bike. (peinture au four)
We must have done a good job with the lines cause a lot of people think we started off a motobecane 40T rigid frame (no suspension) but we just chopped the tail a 50v frame (with suspension) and modified the swing arm. The bike does look like a cool rigid frame because of the small shocks position.

BONUS PIC by Edison:
West Coast master moped builders convention at the Tomahawk shop (Shaw, Christophe, Melvin).
Test run and disassembly.
Puch Maxi Gilardoni 74cc project. I’m gonna machine the cases to fit the wide cylinder skirt + tap for 7mm malossi studs, port the cylinder and cases + mikuni24mm carb + estoril pipe. That kid is gonna fly on that light frame!
LOS ANGELES LAST MINUTE MOPED RIDE TUESDAY JUNE 26th:
Edison’s street BBQ Filipino style is open for business! Check out his blog PSST BBQ psstbbqla.wordpress.com
He’s doing his first test run Tuesday June 26th in Silver Lake at the farmers market 1515 Griffith Park Blvd, Los Angeles CA 90026 (corner of Sunset Blvd) from 4:30pm to 8:30pm. Go check it out!
For the occasion we’re throwing a short moped ride. Meeting is at 6pm at the Tomashop, ending at PSST BBQ around 7:30pm to test Edison’s delicious bbq sticks (chicken, pork, sausage, etc… even grilled chicken booty on the menu). If you’re available come join us and show some love!
Scoot TV on location. Thanks everyody for coming and support Edison’s new street food business.
I’m planning on going to the Myron’s Mopeds ride # 93 (one of the oldest moped stores in LA owned by Shaun) this Sunday June 24th from Fountain Valley to Laguna Beach, CA.
Check out their website for more info if you want to join the ride. It should be really fun at 30 mph max but one open road for fast bikes along the pacific coast. There will be at least 30 bikes. I’m bringing my stock TOMOS.
Back from the ride, it was really fun. Video by Honest Mike:
Here’s the latest Motobecane Av1o project with new custom paint + all the bells and whistles by Melvin (Mel-Mar body shop in Filipino town, Los Angeles).
The bike is almost done, it just needs the pulley + chain. The wheels might be powder coated black. We’re sending the seat to the upholstery shop next week and making white Motobecane gas tank stickers.
Check out all the custom features fabricated by Melvin: swing arm, frame brace, fork brace, disc brake aluminum mount, steel clip-ons, launch lever, exhaust push springs ball joint + seal ring inside, doppler er3 variator converted to clutch function with a brass bushing inside, hidden 6V battery, wiring harness, horn, brake light, key switch, cup holder and even a cigarette lighter… lol
That bike is super fast with a ported Polini W 50cc kit + stock cases, and so torquy that we need to use a 13T front sprocket. We’re going to replace the screaming Giannelli pipe with a doppler pipe to lower the rpms and modify the power band better suited for street riding.
I’m wearing my famous blue latex gloves after pouring a think coat of POR 15 tank sealer in my peugeot 103 rcx race bike to seal a micro leak in an inaccessible area. The previous owner welded a screw on the tank at the base of the fork tube creating a leak that I couldn’t completely fix after few copper brazing welding attempts, the metal got heated too many times in the past.
I designed and got the seat back from the upholstery shop, nice work. The K&N decals might be temporary until we get white Motobecane ones but they kinda look good. Melvin has a obsession with stickers and won’t stop!
As soon as the new seat is on……”sell it!”
Ball joint converted to fix mount based on vintage RGD exhauxt system. No more oil leaks or loss of power. This is a prototype that works great but we’re working on an improved version based on the vintage RGD pipe with “pump” high temperature bellow system with variable length when the engine swings back, from long for low end power to short for top end speed. That system was very effective back in the 80′s and the RGD for peugeot and motobecane was one of the best ans solid pipe. Once we test the final version and like the results we might start making more and sell them.
Test run 1st generation prototype:
I ‘m building a Motobecane av10 engine kick start for a customer in Chicago with stock cases, Doppler 50cc kit, stock head decomp valve (for easier push start “cardboard trick” with Doppler er3 variator bearing clutch function), 19mm carb, dopppler pipe mvt cdi. I’m also testing the new Av10 race crank by 1977mopeds.
You can follow that build here: Moby av10 build… 77 race crank put to the test
I fabricated a quick copy of the missing original kick start unit plate.
Here’s the kick start in action:
Ending the break in session. Carburetion and fuel mixture kept rich.
Final test run: The 1977mopeds race crank passed the test!
I’m sure it would hold fine but the crank would need to be tested with a bigger 70cc set-up with more pounding and vibrations, especially with the heavy stock variator but it passed the test with a 50cc doppler kit high rpm street version with stock head and unmodified doppler exhaust.
The engine is still warm and ready to ship back to Chicago!
I’m going to start using my motobecane race frame to build, tune, test and ship complete engines. So if you’re interested in replacing your av7 cylinder inducted engine or building a fast av10 case inducted engine, just contact me for more details. I will also build a Peugeot 103 test bike for kitted engines or solid 45 mph 50cc sotckish engine. Whatever fits your needs and budget. Moving to a new shop next year, I may start doing it with other mopeds like Puch and Tomos. I’ll continue to take special orders for custom moped builds.
I just received a set of 2 way regular bearings to replace the push start one way bearing on the Doppler clutch pulley and use a kick start unit to start the engine.
Here’s a test run with the HK 3020 bearing.
The stock Doppler clutch pulley is available at Treats moped super store http://www.treatland.tv
I took my motobecane av10 50cc moped for a Saturday moped ride with the “Woolly Bullies”. I’ve noticed that more people are getting into peugeot and motobecane mopeds, yeah! Thanks for the ride and the tacos!
The bike felt really good and the more I ride it the more I love it. I’m actually working on building a faster version of my Bidalot 50cc air cooled engine with stock cases + polini 50cc h20 kit (special porting and nikasil plating) + 21 carb by the end of the year and might sell my current engine ready to mount on any motobecane frame. I finally got the red tongue sticker from http://www.treatland.tv to complete my collection. Thanks Treats!
I found a smaller 54T rear sprocket for better street riding top speed (65 to 70mph) but without losing the quick acceleration. At high speed on Los Angeles bad roads, I’m gonna need one of those cheap NHK adjustable steering dampers. There’s nothing like blasting a 70cc kitted moped with gigantic Gilardoni size 4 petal reed block with your motobecane 50cc kit and stock size 2 petal reed block way more fuel efficient.
54T sprocket for 65+ mph 45T sprocket for 75+ mph
After the ride I made a dual control launch lever allowing to rest my foot at idle by pressing down the rear lever with my heel instead of lifting the front one with my toes. It should be more comfortable for street riding but I can still remove it for the race track. I’ll test next time.
Some videos of the ride and the moby 50cc doppler variator with no clutch in action, holding the camera in one hand and the handle bars in the other (not very safe!).
No clutch = no more problems.
I didn’t know we could buy Motobecane bicycles in the US, they’re cheap too. Now I want one!
Unique… Reliable… & Sexy.
Custom moped Motobecane Av10 50cc
The engine feels just the way I anticipated it. I can tell by ear that we’re close to 11,500 rpm. Not bad for a beat up 50cc Bidalot kit with an old nikasil. When I looked at the small ports I never thought that kit could rip but I increased the port duration to Gr2 specs and it worked. I was afraid to lose some low end power with the new port duration but it didn’t happen, even with a standard pulley. I can’t imagine how good the bike would feel with a clutch pulley. In general, Gr1 set ups are not as powerful as Gr2 or Gr3 but have more torque.
Overall the bike feels good, not quite as powerful as my Peugeot 103 Rcx 50cc h20 but close with more torque and way lighter. The downside is that it’s an air cooled engine so it won’t stay as consistent during the entire race, especially if it gets hot in the desert.
Today I finished all the electrical on the bike which is usually my least favorite part but it’s much easier on a race bike than a street bike. I didn’t have to deal with lights, brake lights, regulator, etc… All I had to do is connect the cdi box + the kill switch and it was done, loved it.
I checked the brakes and made sure that everything on the chassis spins freely without slowing the bike. everything feels really good and the bike still feels light.
The chain slightly rubs against the swing arm. I’ll take care of it by shaving off some metal and building some kind of rubber chain slide. By the way, those are all the sounds you hear on an electric bike.
It’s funny because every time I pull a new bike out the shop the neighbors either give me a big smile or stare at me with curiosity like if I just landed from outer space.
