Curse of the mountain bikes: Part II

I haven't written in quite a while so lets get right to it. I apologize to my readers for having to wait so long for part 2. Here it is. So my dad decided to ditch the first bike and went off to buy a second hand thinking that the price range was 2 to 4k . We however abandoned the thought of buying a new bike after hearing the prices. And what were they charging for those old , rusty bikes. 8k! We went off to buy a new bike at a familiar place. Yeah it was familiar cos call me stupid it was the same vendor who sold us my first bike. I decided not to tell my dad cos i was desperately in need of a new bike. Today i regret that decision! The bike was just 6k! When the deal is too good think twice! But the damn thing looked good n it still does. Made of shiny metal. So we took the days purchase home and i took it out for a test ride. On the way to the field i met some kids riding a borrowed bike. Since mine had a 'passenger seat' on the kids requested that i carry his friend n i did. We rode through some tall grass and up a hill. Suddenly the bike pedals felt loose and however how much i pedalled, the bike didnt move. I looked down and saw the chain. It had broke off! Luckily the vendor had told us that we could take the bike back anytime for repair. I returned the broken chain and it was replaced. Stupid bike! Spoiling on its first day of purchase! Yeah that was just the beginning. Before i rode it i had adjusted the seat to suit my height, but even after tightening it , the seat would easily move back and forth like a seesaw depending on where i applied pressure. Solution: i replaced the seat with that of the old bike. No more problems. After some days riding, problem no3. The right bike pedal , started getting loose and soon enough the part of the pedal where the feet is placed fell off. I tightened it with pliers. Days later it fell off, i got hold of a spanner n tightened it tight. That worked. Damn thing has never fallen of again. Later only a minor problem, the back mudguard become loose after the screws came off but i kinda used a hook and crook method to hold it back into place. The bike stayed problem free for sometime and was promising. The thing was fast and i could ride for long without fatigue. I even rode all the way to Shanzu n Mtwapa. For a good period of time, it was the best bike in the world and the bike of my dreams. It still feels like that once in a while nowadays. Holiday over! One day as i was riding to Shanzu, a new problem occured. The back tyre loosened. It became loose in a freaky way. I heard something fall and the bike started moving irregularly. I checked the back wheel. The two nuts were still tightly in place and tyre seemed to have been disconnected from the central metal cylinder as it moved loosely like a milk tooth. The bike was taken back to the vendor for repair. It was repaired. Unfortunately when my dad was putting the bike in the boot, the left gear changer broke. Like it broke into pieces. I tried riding it as it was but changing the gears using the right changer didnt seem to work. The bike was unridable. My dad told me that we would replace them with that of the first bike. I decided to do so on the second day only to discover that my dad had already ruined the right one. I opened up the left one and discovered why my dad had ruined the other one. Once u opened it, it couldnt put it back again cos of some spring, furthermore the changer was connected to the gear wire and thus to remove it meant removing the wire too. Cumbersome! My dad took it back to the vendor anyway. The gear changers were replaced and they still work ok. Next just after a few days after the back tyre had been repaired the front followed the same fate. It became a loose baby tooth so i replaced it with that of the first bike, remember the one that had a high quality tube? Yes that one. Oh it made it worse ! It reminded me of the crappy first bike that was so slow. Still up to today i dont know what makes it so slow. Even if you pedal your hardest, damn thing will just move like a wheelchair. I don't know why but it feels like there is some resistance at the pedals. A few km of riding leaves u exhausted like a goat. I persevered and on the next Saturday took the first tyre out and have it to my dad to take it for repair. That seemed to work. The only problem even after repairing the bike was the resistance when riding. It soon eased of a bit but pedaling became quite hazardous as the pedals will seem to get stuck and suddenly get loose and if riding too fast, this will cause your feet to leave the pedals and you loose control. This would occur once in a while but it started happening more frequently and the gear stuff and the back would seem to be jumping like as if something will get stuck ,pull it, let go and them get stuck again. My dad took for repair and we were told that it would require another gear machine stuff costing 250. That never seemed to fix it...
