OK I see what you mean; it wouldn't suit me on the road at all (wrong gear ratios, horrible Q factor) but I guess it could work for some folk.

If I had these bits in my spares stash you'd be welcome to them, but you know what, I'm fresh out...

cheers

I am using the same Shimano chain. The wear indicator on my Park tool says 'good' after 9300 miles.

The weight savings are as follows:

Tektro 560 levers and Single shifter vs 105 ergo: 275g

Cables 1x Bar end vs full ergo 145gr

Front mech band on 140gr

2x chainring 205gr

Saving in reduced chain length 55gr

Total: 780 gr = c.2lbs

You should try the set up yourself before you judge...

Not really, because the chain line is optimised for one set up, so there no extremes of big ring/big cog and vice versa. The low maintenance aspect is twin: no front mech/lever/chainring adjustment or wear and drastically improved chain wear.

I used to go through a Shimano chain every 3000 miles. I'm on 9300 miles with this chain and still going strong.

Using a bar end shifter I was able to save £285 over a 3x11 set up which tbh I wouldn't consider again.

A 1x8 set up could probably be put together for £120... Oh, and it also shaved 700gr (2lbs) off the weight of the bike (with 3x10)
too

There are quite a few YouTube videos about chipping e bikes to to do 35mph+

Obviously it rattles the battery but what fun,

Childish Pete...? You've obviously never had the joy of passing and dropping a full SKY rig out rider on their brand new Boardman

I think speed is the real Achilles heel of any E bike. If I were to be tempted to buy one it would have to be at least as fast as a good moped and preferably able to keep up with cars in fast traffic. I can't see the attraction otherwise, especially if it's to take off with commuters.

E bikes parts = Commerce = Maximising profits

I did 104km/h down the biggest hill round our way last week on a £9.99 Schwalbe tyre.

It looks perfectly okay to me

I've been riding a 1x11 set up all winter and I must say it's all the gears I'll ever use and very low maintenance.

Im liking these two devices: Road bike rear suspension (appearing on a few bike this season, keep an eye Paris Roubaix) and removable battery charging for multi use devices.

GPS signalling handlebars with WiFi and Bluetooth already with us but unfortunately no haptic feedback yet

8. Always on 360° 4K video scanning and recording. Automatic reporting of collisions/NEAR misses/driving too close to Police/DVLA and drivers insurance company with auto upload of relevant footage. This is quite possible now.

9. Free contactless charging for any bicycle need at supermarkets railway stations etc

10. GPS integrated into the handlebars with haptic feedback to indicate what turn to take next.

The same journey to the Isle of Skye would take a whopping 16.5hrs. Roughly the train journey time from Paris to Rome (1450km)...!

Just checked the average journey time from Liskeard to Oban and it's 17h58min!!!

Tight budget

Technology seems to be sprinting onwards, especially battery technology and materials.

Things I'd like on my (everyday) bike in 2020

1. Tyres which are quite literally puncture proof

2. Carbon frame which is as durable as current steel

3. Lighting which can be recharged from energy recovery from disc braking

4. Lighting which is as powerful as a car lighting system

5. Direct drive or completely sealed very low maintenance transmission

6. Proximity sensors when cars come too close, and audible warning both to other road users and INSIDE the offending vehicle.

Just a few for starters .

Worse than useless. I had to repair a tube the traditional way last weekend when a glue less patch failed.. In the pouring rain. 2 minutes later and we were on our way again. Glue rules!

BTW the one thing none of these courses teach is how to put together a good, comprehensive tool kit. Something you would think absolutely fundamental to the job!
