Time to enjoy cruising the streets of LA.

I’m rebuilding the bike with slow precision like a meticulous surgeon.

I don’t know all the details but I’ve learned through Neil the organizer of motorized bicycle racing in Southern California that a group of people drag race old mini bikes in the streets of Long Beach (south Los Angeles). It started just as a ride and BBQ event but now it got really serious with bikes going 90 mph and racers talking trash. Check out the Oldminibikes.com forum for more info.
It’s the final phase, time to rebuild the ultimate Peugeot 103 street moped.

Small steel parts flat black powder coated by Pyramid Powder Coating in Sun Valley.
Today was the last day before the very first start of my Peugeot 103 streetfighter. I finished all the electrical wiring but I’ll make it look cleaner once I reassemble the bike with a new paint. It’s hard to hide all the wires with so many electrical components. I decided to keep the mini fuses protecting the electric pump and battery circuits exposed though, for a quick and easy access.
To save time I decided not to test ride the bike, I’ll do the final tuning once the bike is painted and reassembled. I will also have some stainless brake lines custom made for the front and rear disc brakes.
Tomorrow is the big day. Hopefully I’ll be able to start the bike and post another video. I took my time and double checked everything but you never know with mopeds, anything can go wrong. I’m keeping my fingers crossed.
The bike is 90% done and ready for a paint job. I can’t wait to blaaaaaaast the streets of downtown LA late at night, sitting far back on the saddle with a tight grip on the handle bars.
Yeah! T-hawk is finally born and took its very first breath of oxygen in Hollywood Griffith Park. The bike is so sexy that it already got harassed by people jumping out of the bushes.
The engine fired up right away, it’s not tuned yet but has an awesome sound. The bike feels really solid with no resistance in the wheels, chain or rotor discs. It’s a little heavy with all the equipment but that will increase the stability at top speed and keep it safer on the bad roads of LA. It actually feels and looks more like a small variated 70cc motorcycle and not much like a moped anymore, kinda like top tank mopeds.
It’s now time to disassemble and paint all the parts. Once the bike is done I’ll post some photos and videos of the test runs.

I’m starting to see the light at the end of the tunnel and should be able to fire up my street bike project very soon. I’ve been waiting 2 years for this moment.
Today was important, I hooked up all the water hoses to the motobecane stock radiator, the temperature sensor and the electric water pump. I just need to wire the pump to a regulator/rectifier or a small separate 12V battery.
Here’s what’s left on the list before finally starting the engine and do a bunch of test runs before painting the bike:
Finish all the electrical wiring (cdi, regulator,battery, fuse, water pump, vapor tachometer + temp gauge, lights, kill switch), lock the pedal shaft so the pegs don’t spin, custom make heavy weights for the malossi variator + the doppler spring way too strong, install the chain, the disc brake lines, the throttle + cables, mount the motobecane engine mount rubber bushings (rare on a kitted peugeot frame but recommend to absorb the vibrations and prevent breaking parts like the exhaust, etc…) Now I wish I would have bought a 50cc h20 engine for less vibrations and overheating problems but at the time I had the “small piston complex” and wanted the biggest bore available like everybody else. That being said, the bike is so heavy that I might need the torque for a more comfortable ride and forget about a screaming engine or top speed.
Few hours away…
I just have to finish all the electrical wiring, install the throttle + choke cables, the fuel line, brake lines and I’m ready to fire up this bad boy!
We learn everyday. I just found out on Facebook that the peugeot 103 RCX/SPX engine is actually rubber mounted and the mount comes in 2 brackets connected together with a thick square piece of rubber between them. It seems like you take the engine down by just removing the bolt on the lower bushing and leave the black bracket on the frame. The more popular 103 SP version in the US doesn’t come with rubber bushings, the bike vibrates a lot with a powerful kitted engine often braking the exhaust. The answer might be to modify that engine mount by welding a rubber bushing just like on the 103 spx (left photo). The big polini cases with aluminum arms vibrate and sometime a powerful engine set up brakes the arms. The best cases are the malossi ones with 70cc kits and 21 mm carb minimum or the smaller polini cases (but expansive) using the stock peugeot mount steel bracket (maybe reinforced or rubber mounted would be the best) with a 50cc kits 19 mm carb max.

I’ve been busy lately but the bike is slowly starting to take shape.
I fabricated 2 custom gas tank covers, sanded all the welds on the seat and custom made a 2 piece front fender out of an old plastic one. There’s still a lot welding to do and I need to work on the liquid cooled system but I’m getting close to the final phase before painting. The bike is a little heavy with all the extra parts but I wanted to concentrate more on aesthetic than performance.
Bonus pics, the bike’s 1978 stock version when I bought it in 2009, few of my Peugeot chrome emblems bought at a scooter shop in Paris and my collection of TREATS stickers. I want a red tongue sticker so bad… will you give it to me?

Peugeot 103 polini street races at 95 mph apparently (Algeria). Their bikes our loud because they remove the exhaust baffle. They use 70cc kits that don’t rev very high with the smallest rear sprocket available. They need super long roads to be able to reach top speed but they’re fast.
I’m finally going to finish my very first project and personal street bike.

Look, master builder Christophe may soon be able to do club rides again! More updates to include all the crazy Euro parts and stylings on this bike. Headlights are not final but stacked cateyes under consideration.
