Back on track.. (i dont know all the proper terminology for a lot of bike bits yet..)
tldr- Lots of arghhh due to bike bits agro and rust, not a huge spend required tho..
The yellow TAICO-02 bike, Needs a bloody redesign. gear cables fed through open holes in the top of the drop tube (diagonal from steering head to bottom bracket) so water gets inside and pools at the bottom bracket rusting its bearings and encapsulating fittings in the aluminium frame..
I tied the frame down Bolted on the bottom bracket extraction tool to keep it in place and used a 6ft lever with my circa 100kg mass behind it in an attempt to shift it, naa the bolt securing the extraction tool in place decided to stretch and allow the tool to skip teeth, and again after retightening down hmmmmm
Then i went stone aged impact driver at it for a good 1/2 hour with a cold chisel and hammer
However after lubing with penetrating oil targeted at the threads the bearings feel less crunchy (wishful thinking?)
I dont feel like going full out destructive with a torch yet so have decided to live with a crunchy crank to start with and may well revisit or even pass the buck to a pro bike shop.
gear wise,, its been 'upgraded' from a 7 to 9 speed freewheel, the rear frame has been stretched to accommodate this and requires wedging to remove or fit the wheel.
the rear derailleur and shifter work ok with a new cable, although the shifters indicator is not registering changes . The chain wants to jump between the different chain rings when the rear gears shift. the front shifter is seized atm so is soaking ,, smaller freewheel and new chain would be good imho.
Ive opted to buy a new 17a KT controller and lcd3 headset with waterproof julet connectors along with the suitable cables and new brake levers and sensors to replace the defunct controller and headset, although the existing sensors use higo connectors and not julet, the cables on the brake levers are worn revealing inner sleeves to further damage and i have a spare pas sensor already, so am about to spend close to £90 with aliexpress to put the bike on the road with its crunchy crank.
The red/orange bike with the HUGE 48v motor .. Again rust is the major issue seized solid chain crunchy crank tho the bottom bracket looks easy to pull,, its not rusty.. and rusty forks.
no gears are fitted to this bike although the motor wheel has a 7 speed freewheel fitted.
with the wheel in the vice and it all wired up and powered as is the broken display shows nothing but lights up and the wheel responds to the throttle.
The wheel is a wreak 8 broken spokes, and the hub shifts left to right up and down un supported by the remaining spokes
So i have orderd new spokes and will replace them 1 by 1 staring with the broken ones and the cutting and replacing the rest..
I can use the 6speed freewheel derailleur, chain and shifter from my base donor bike
so with a successful bottom bracket exchange £30 should get this one rideable, but not on road
