In response to
@RustyIron's post about losing your mtb mates. I had already stopped riding with my mtb mates. They were all younger than me and untroubled by arthritis. I hated the thought that I was holding them up in the climbs and reducing their fun. They were mates, so they never said anything, but I was a mate, so I chose the rides I went on to minimise the impact, (long climbs were my downfall) then eventually my distances dropped, so I stopped riding with them altogether.
Then I bought an emtb and I was reborn!
But when I rode again with my mtb mates, it was like Rusty said, but not quite. I did not romp to the top of the hill and crow about it, I hung back. But when we got to the flat sections, they didn't hold back at all, but blasted along at their top speed, which was a lot more than the 17mph that I could manage on my non-spoofed bike. When I caught up there was the usual joshing about tardiness, but aimed at the bike. I was starting to feel a little bit disenchanted with them. Then I went on a meet-up with other emtb riders, none of who I had met before and it was BRILLIANT!
I tried to keep in touch with my mtb mates, but one by one they all slipped away. I now ride with a different bunch and they are all great fun.
@Pace 1234 get that emtb bought, do it on 0% interest if you can. JE James and other bike retailers do it (called "V12 Finance"). Even if you can afford to pay cash, it is better to keep that cash invested or available, because you will gain from that. Zero % interest will cost you nothing, and you can pay it off anytime without penalty if you wanted to do so. I left my money in Premium Bonds instead of cashing them in to buy my bike. You never know this time next week, I could be a millionaire!
Edit: Look out for the Rideouts, where you can meet and ride with like-minded individuals.
