This project
came about by chance because of a bike I was asked to undertake a
small repair on. It was a child's Felt bicycle which was a bit
different from the normal kid's B.S.O.s (bicycle shaped objects).
The bike had a nice frame and some nice components but was very,
very, heavy. I wondered at the logic, which married some good kit
with the very heavy mediocre, to produce a heavy kids bike with
pretensions, at a hefty price tag. As chance would have it, I came
across a Giant 24” wheel aluminium frame MTB that was heading for
the scrap bin.
Could I turn this ugly duckling into a swan that
might fly? The frame was sound, but all the cheap, heavy components
were badly rusted and the bottom bracket and headset were shot. The
bike was put to one side of the workshop. The occasional glance
while working on other things started the the ideas train rolling.
The first task was to strip the bike down to the bare frame. The
challenge was to see if the bike could be rebuilt, firstly, to make
it a lot lighter and secondly, to produce a good quality child's bike
on a budget. I am aware of Islabikes as being the only bicycle
manufacturer in this part of the world who produces good quality
children's bikes and is not committed to the 'heavy kids clunker'
concept.
The
penetrating oil was reached for and liberally applied. With patience
the bike began to come to bits and the scrap pile grew exponentially
on the workshop floor. Once the frame was stripped down and the
heavy, rusty suspension fork and headset removed, it was checked for
visible signs of damage. Some minor scrapes to the paint finish but no
obvious sharp impact damage. The bike was originally fitted with a
six speed freewheel. The cost for rebuild had to be kept under
control, as the bike would be sold on, once the project had been
completed and must produce a return for the work carried out and
parts fitted. The original wheels were steel hubs laced with
rustless spokes into an alloy rim. The wheels were heavy and out of
true. The spokes were corroded, so even attempting to true them was a
complete waste of time. Replacement alloy wheels would be fitted.
I
gave some thought to building wheels using a cassette rear hub, but
rejected this on the grounds of cost. I used stock 24” replacement
wheels, alloy threaded hubs, stainless spokes and alloy rims. I also
fitted a 7 speed freewheel. The bike needed new suspension forks and
after doing a bit on online searching identified the SR Suntour XCR
as the best model available for 24” wheels. More online searching
produced a heavily discounted purchase. The
replacement headset was a stock item and the fork steerer column was
measured and cut to size before fitting the star nut inside the
steerer tube. The forks were then fitted and the headset adjusted.
Turning my
attention to the handlebars, I saved the original alloy stem, but
dumped the rusted steel handlebar. I managed to source some narrower alloy downhill bars which were remaindered stock.
The bike
originally had a cheap bottom bracket set comprised of separate cups, ball
bearings and axle. I chose to replace this with a sealed square
taper bottom bracket unit and a new alloy Sunrace triple chainset.
The original derailleur mechs were heavily corroded and I chose to
replace these with a rear Shimano Altus mech and a Shimano LX front.
A new chain was also fitted, along with Sunrace twist grip shifters.
I had considered using rapid fire levers, but after talking to my
youngest daughter, went with her preferred choice, for ease of use –
twistgrip. The drive train was then cabled and adjusted.
The steel
seatpost was scrapped and a branded 'Giant' alloy one bought on ebay.
The original saddle was saved and refitted along with the Cateye
reflector.
The alloy V brakes were cleaned, refitted, recabled and
adjusted. The new wheels had been given, new rim tapes, but the
original inner tubes were reused as they were sound. Tyres were then
fitted. The bike is much lighter than the original spec and the drive train works well. My
youngest daughter has road rested the bike and declared it good to
ride.
The bike is
a one off, but has proved it is possible to produce a reasonable
quality, relatively light, child's bicycle, which is durable without
breaking the bank. Is there a market for this sort of bike? I
believe, yes, however, it has to come with the caveat that the market
is a small niche, in the overall scale of children's bicycle buying.
Why do I say this? Firstly , on the evidence from Islabikes, who sell directly
to customers via the internet, servicing a global market and secondly, I don't know too many families yet, that use bicycles solely for transportation. The majority
attitude towards children's bicycles in this part of the world seems to be, that they are toys and are bought through toy shops or supermarkets.
A £60 BSO (bicycle shaped object) is considered a good buy. The
fact it is incredibly heavy and therefore tiring to pedal, over anything other than a short distance and has to be assembled from the carton,
is not an impediment to sales. The number of children's
bikes bought through cycle shops here, has dropped dramatically and
the once annual Christmas bonanza for the LBS of children's bikes
has long since gone. Children's bikes are considered as a 'throw
away consumer item'. This may change as more adults start to ride
bicycles again, but I believe attitudes will only change significantly, when the
bicycle is being used for transport, not just recreation.
