Getting laid back on my bike

At Christmas I entered a sportive whilst worse for wear but duly set about a training regime to put me on course for a 65 mile bike ride. The training regime started a bout of bursitis which then mutated into a flare up of all my spinal complaints and now apparently my neck has degenerated to such a state that I need to take extra special care to extend its’ useful life.  I have now spent more than ten weeks getting needles stuck in me at my expense in pursuit of pain free existence.
I have always enjoyed the stranger sides of transportation. I had a rat bike (take a bike, take everything pretty off it, take the remainder and paint it matt black) I built a car, I drove kit cars and I supported the stranger sides of cycling. So my decision to invest in a recumbent bicycle wasn’t exactly a last ditch attempt to keep on the road but that desire was very high on the list.
I kept fairly quiet on the subject at the time, this was a decision I needed to make for me and I actually didn’t want any external input to dissuade me. I test rode a number of bikes and trikes under expert tuition from Kevin, the owner of DTek in Ely and from that moment I was sold on the idea. The positives were clear, no pain in my back, no pain in my elbow and no pain in my neck. The negatives were also clear. They cost a lot for what they are, they look strange and they handle differently. I wasn’t phased by this and I felt that  the purchase was justified.
I bought a second hand Challenge Furai from Kevin at DTek for a sum not far short of the Greek  national debt. The bike had everything I thought important, a bit of suspension to prevent all the bumps going through my spine, 24″ wheels to provide me with less distance to fall, subtle matt black and decent specced  drivetrain and brakes to make the experience all the more pleasant.
You know how it is when you are sold on buying something and the salesman make a glib, throwaway statement?  A statement that if you were less sold on something would trigger an alarm bell. You know how it is when all you want to do is press the buy it now button on the card machine and something starts a little beeper in the back of your mind, that you instantly override?  Well both occurred on that fateful day and I knew better.
The first issue was the statement that anything, even slightly dodgy, would be replaced as a matter of course, then during a phone call being told that the tasty Hope brakes were buggered and needed replacing. Replacing brakes doesn’t come cheap. Therefore anything aside from the brakes would have to be passed on or Kevin would be out of pocket. I understand business and I live in the real world, this is life.
And so I arrived back in Ely to test ride the Challenge Furai with a view to spending an indecent amount of money on securing it for my future entertainment. Only to be met with a throwaway comment about the tyres, being close on the limit of requiring replacement; good tread, cracking sidewalls but not bad enough to warrant changing. The test ride was brilliant, though shortened by the gale force winds. We were soon figuring out the best way of strapping it to my car.
On the journey back in those winds we stopped to check the bike. The rear tyre was flat, this was a surprise but I ignored it. I fixed the  flat and set about monstering the bike around the campsite, learning the subtleties of being a bent rider. The next day, the tyre was flat again. I bought another tube and continued the learning curve.
I managed maybe 35 miles on the Challenge doing the local safe routes before setting out on my first major ride last Thursday. I had got about seven miles into the ride and realised I had yet another puncture. I changed the tube but for what ever reason, the tube wouldn’t inflate. I only had one CO2 cartridge left (and stupidly no patches with me) and this wouldn’t last to mess about finding a leak and inflating the tyre and so began the long walk home. On this walk I then gained a front wheel puncture just by pushing the bike.
On my safe return home I decided to buy new tyres and new tubes ahead of my weekend away in Wolverley. Due to the last minute nature of this purchase only next day delivery would do and the only retailer I trusted didn’t have any suitable tyres so I bought what I thought would do. Imagine my joy at the timely arrival of the package and my unbridled dismay when the new tyres were completely the wrong size for my wheels.
Fortunately I have other bikes at my disposal and so the weekend hasn’t been ruined but I was so intent on spending the weekend riding my recumbent. 
And so the search for tyres began again. It appears that 24″ tyres aren’t that popular and 1.5″ width even less so. I can’t help thinking this fact was known to the retailer and glossed over. I haven’t raised this with him personally and I doubt I have the bottle or the reason to do so but for a while I was genuinely feeling I had been sold a dud   I have now bought some slightly wider tyres in the hope they will fit. If that fails, I will try and convert the bike to larger wheels but still wish I had had the tip prior to purchase, it may have changed my decision.
On the aforementioned fateful day, most of the time was spent trying to get the gears to work properly. The bike was very prone to ghost shifting and a generally lack lustre experience. Me being an expert on crap gear shifting soon had me making an attachment to my workstand  and checking the alignment of the rear deraillieur with my specially made alignment tool. After 5 degrees of alteration, the gears finally started doing what they should do.
Whilst all these niggles appear easily solved, should I have had to deal with these at all?
