Keep the one you love the most and sell the rest. Having a spare analogue is always good for when the ebikes are out of commission for whatever reason. Besides the analogue bikes are losing money and becoming out of date. Let someone else love them!
My old bike. Had it for twenty years one of the first in the country. There was nothing else out there I wanted. Done thousands of miles on it riding like I stole it, I should not be here the way I rode that bike but it felt like putting a pair of slippers on and as things broke I upgraded them. Wish I had kept it now.
Still got my Giant Escaper, bought new in 1993, cost about £550 if I remember which was a chunk of change then.
There's a brand new one for sale on eBay, in Italy, at the moment for £519. I should have held on and got a bargain.
