New bike projects underway

Projects Update 2016

With lots going on recently at Artisans Collective CIC, Prestatyn Dementia Friendly Community and Prestatyn Men’s shed my personal bike projects had been placed on hold.

Jayne at Surf Snowdonia with our 1990 Mazda Eunos that is fondly nicknamed WTF due to its registration letters.

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.

Latest Concept

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.

Delta Wing Racing Car

I have always like the unusual, and really love the Delta Wing Concept. I have followed the designer Ben Bowlby since watching a UK Channel Four equinox documentary called “The nuts and bolts of Ben Bowlby”. In that programme he was designing a clubmans car, a class that I later raced a car in.

Originally designed by Ganassi Racing Technical Director Ben Bowlby as a successor to the outdated IndyCar chassis, the DeltaWing is not just about looking different – it is about transforming the motor sports and automotive industries with radical innovation. Racer magazine called it a “game changer”.

As he watched motor sports viewership decline worldwide, Bowlby looked at the smaller format engine technology that was entering the forefront of the automotive industry.

He realized that this technology was eminently relatable to racing fans. There had to be a way to use a small engine to create an entirely new package-one that would be more efficient and still give the performance that a premier race car demands.

Currently the car is racing in IMSA in the US and was this weekend going extremely well at The Daytona 24 Hours with the UK driver Katherine Legge at the wheel, until an accident whilst driven by one of her team mates put the car out of contention whilst competing for the race lead.

The Press release from the team is below:

Panoz DeltaWing Racing made history today with Katherine Legge taking the coupe to the front within the first hour of the race. “We’re really at a stage now where we’re showcasing what it’s got,” said Legge when talking about the car. “I’m proud of the team, I’m proud that they gave me a really good car, and I’m proud of the job that I did, as well.”

The coupe consistently ran at an impressive pace, at first chasing then passing the leaders. Both Legge and Andy Meyrick led a combined total of 29 laps out of the 119 completed before disaster struck when the coupe made contact with a PC car sitting stationary on the track.

“It was very unfortunate. The car was in a blind spot with no lights on and it was unavoidable,” said Meyrick. “The radio was intermittent and unfortunately the combined situation resulted in an accident that caused a very successful day to end too soon. I was catching back up with the leader and it’s a real shame we weren’t able to get back up there and enjoy the result we should have had.”

Specialized Rockhopper bike in the workshop today

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 !
