August was also very busy with work away from Prestatyn including a PR trip to Glasgow for Grow Wild. Also I went back to my roots adding a Mazda MX5 Classic sports car to our projects.
I have installed a new radiator, sound system, windblocker, cockpit brace, and am currently renovating a hardtop for use in the winter. I raced a couple of similar cars in UK race championships a few years ago. They are really nice to work on.
Having entered the Great Orme sponsored bike ride for charity again this year, it is time to consider what bike to use, last year I used the trike that I built for Jayne.
This year I am considering designing, building and riding a 2 wheel drive electric bike.
The concept will use a 300 watt rear wheel and 250 watt front wheel to aid stability. I hope to be able to utilise a single Lithium-ion 36v 15ah battery. My calculations say that that would give just over 1 hour of power at about 25mph, when off road.
The current regulations limit electric bikes to 15mph and 250 watts when used in public areas. I propose to just use the front wheel drive when on public roads and enable the rear wheel drive when off road.
I will utilise the bog standard Universal bike for testing the concept before building a higher spec bike if the concept works well.
If it proves successful I will build the mark two version around an aluminum framed mountain bike with suspension and disc brakes.
Specialized Rockhopper my Old School favourite hardtail bike.
Specialized Bicycle Components, Inc., more commonly known simply as Specialized, is a major American brand of bicycles and related products. It was founded in 1974 by Mike Sinyard and is based in Morgan Hill, California. Their UK website is here.
The rockhopper model has been in production for over 20 years and has been constantly evolving into the model below which is the 2015 version.
The version we are working on today has really good rim brakes and twistgrip shifting, of which I am not a great fan.
The bike has a problem on the front derailleur that has not been cured by the fitting of a new chain and twistgrip.
So today we are upgrading by fitting a new Shimano Deore LX front mech.
Also a side stand, rack, panniers and bags to enable the cycle to be used as a daily commuter bike are being fitted.
I will be removing the old Shimano front mech by drilling a rivet out of the cage on the shifter mechanism, to avoid the need to split the new chain. The new mech already has a removable bolt to allow this.
The new mech has made shifting much easier and smoother, with less effort needed at the twistgrip.
It did take quite a bit of setting up, as what felt right in the workshop needed a slight tweak after a road test and lubrication of the chain and gear set.
Fitting the rack and panniers has added weight but as the bike is being used mainly on the daily commute this is fine as the space to carry equipment to and from is essential.
Not a bad half hours work and it is only 8am now !
