1981 Motobecane MX10

(1/5) > >>

Chilli Rinse:
I found another cheap French bike on eBay France to play about with. At ?70 for the frame set including the headset, bars, bar pad, stem, levers, grips, seat, post, clamp, nos chrome Rigida wheel set with patina, new tyres and tubes, how could I say no. The shipping and vat added to the cost but still a good deal I reckon. Apparently the MX10 was the first Motobecane BMX available to buy, not quite convinced about that though ! She arrived today so I set about unpacking her and loosely piecing her back together.

I had some Rigida Superchromix 20x2.125 wheels that had already been cleaned and greased sitting about. So I bought some cheap all black snake belly tyres to use instead of the all yellow Kenda Krackpot tyres that were included in the bundle. I have a Motobecane branded Takagi crankset and a pair of Weinmann 1020 calipers in slightly faded black to be used. YST bb on the way, I just hope the 130mm spindle works out ok. The grips are spec I think but they will be uncomfortable so might go with some yellow Oury waffles or OGK Mach grips I have. I'm sure I've got some generic black cables to use too. Black chain on the way too.

I nearly forgot about the black HTI rat traps, they will be used too.

This should be a quick one  :LolLolLolLol:

That's cool. Many years ago a buddy of mine had a suspension bike from the 70s made by them. It was luminous yellow, IIRC. It was so heavy you couldn't ride it, and so bouncy that all you could really do was get it out and bounce up and down on it like a pogo stick that never leaves the ground.

Was great fun, mind.

Sounds like good exercise  :LolLolLolLol:

Update... hit a problem already. The Takagi crankset, although it has jis tapers, the pedal threading is actually French. I guess it was produced exclusively for the French market being Motobecane branded. Problem is the HTI pedals are standard 9/16, so the crank arms are getting tapped out to 9/16 soon. PITA already, not such a quick build after all

Last night I spoke to dad about my crank and pedal problem. He knocks up these 9/16 taps for me to use. Trashed a pair of spare pedals he had knocking about, cut two slots in each spindle. They worked a treat, perfect threads for the HTI pedals.

What a star ⭐️

Thank you dad  fistblump

Taipan:
Is the M logo in the gussett a decal or is it cut out of the metal?
