I really joined this group for your very needed expert advice in my on-going DIY repairs / replacement / improvements on my 1st (very CHEAP-Walmart) Hyper E-ride 26 MTB. I purchased it at the end of last year when my 1970 (my father's old hand me down skinny tire) bike failed on the Bike Trail with a ride with my Grand KIDS. The Hyper was a great upgrade (that did not break the bank). BUT - I have made a lot of improvements and replacements since then Aug. 2021 and this year Aug. 2022 I have ridden a total of 250 miles (I have some age 76+ and arthritis issues) on Bike/Walking trails and neighborhood roadways. I have made some major changes - Seating Position to a Dutch style upright bike - hydraulic rear brake - thumb shifter. I will be looking to YOU-ALL for your expert opinions and advise. Thank you in advance, IT'S GREAT BEING A BIKER (or should that be a CYCLIST?) !!
