Hi Allan, thanks for your reply. In response to your question about the type of device to electrify your bike, after a lengthy and arduous research period, I chose "The Boost". Here is the link: https://www.boostbike.uk; your other question is what type of handlebars, my Ridgeback Expedition has drop bars with "Bar-end shifters, panniers and old style cantilever brakes, quite heavy, but I am carrying photography equipment and not in a race, and with 27 gears it make it a bit easier to climb, some hills but only some rest is walking, but not now, my dashboard with GPS, Phone, Smart watch, moniters my heart etc, "even a bell "yes a BELL" most road cyclist "DO NOT HAVE A BELL or it seems a MOUTH, really annoys me, when not even warning (I AM COMMING THROUGH) me they are going to pass! , cant tell how many I have knocked off when stretching my arms, all because they could not spend £3 on thier very costly £3-5k bikes, I rarely go on roads try to stay well away, seen far to many incidents on over 60 years of traveling, another thing that bugs me is, Why do road cyclist wear "BLACK" all BLACK" they dont realise they are just a trucks or car wiper blade away from trouble and wearing BLACK, same colour as the "BLACK ROAD " or wiper blade, BLACK is trouble for all vehicle drivers trying to see or maybe not seeing them in area's where their is shades from trees, tunnels, buildings, all dark shadows even the Sun, they are a total problem in Black to see, yet the drivers get the blame, why do Police and Emergency service all wear bright HI-VIZ clothes, workers everyone wants to be seen, all except road cyclist ,,should road cyclist have insurance is another question (just asking ),they can cause an accident and write off a car or injure the occupants, but they pay nothing,yet the vehicle owner has to pay more for accident insurance afterwards (end on rant). This is my enjoyment, OK the bike is a heavy old bike but it is my BIKE, and My joy to ride, used to see our area from a historic view of befor and after, streets, building or even people, all this for my little Facebook website, Pelaw People Past & Present, now with over 3500 members, my latest piece of equipment to make it even heaver is a small "Drone " for arial views. My old "Mule" has completed challenges for Cancer UK, on the C2C, Ravenglass to Tynemouth solo with all loaded with camping equipment and cameras, more runs, Seahouses. Edmundbuyers, my normal Sunday run was (hope to get back to that soon) to Tynemouth via the Tyne Tunnel or ferry, returning a long way round to Newcastle, Gateshead, and back to Pelaw, about 20 miles. I hope this helps. The Boost system is very light and very safe, hence my choice. Hope everyone enjoys my explanation (just my personal views), or maybe starts another conversation regarding my comments.
