17,344 mile, 8 Year Update
Another great year riding my 2015 Haibike suro Hardseven SL Yamaha. The 21st of March marked the end of my eighth year of ownership. I recorded 2,046 miles for the year, and ended with a total recorded mileage for the bike of 17,344. It is no longer my ride to work bike now I have retired, but instead fulfills a very useful role as a leisure vehicle that helps to keep me active and fit as well as carting a fair bit of shopping.
Transmission
One highlight for me this year is that the cassette and chain ring lasted for the whole year as well as half of last year after initially being fitted back on the 30th of September 2021. That was my last big transmission TLC overhaul with at the same time also fitted a new chain and jockey wheels as well as a thorough cleaning and un-gumming of the rear Mech.
This is further than I have previously managed out of a rear cassette, and the cassette and chain ring together completed 2,728 miles. This is probably because now I am retired I do less higher speed road miles that used to wear out my top gear 12 tooth cog.
From the start I kept an eye on chain wear and changed the first chain at the .5 wear limit, putting another new chain on and keeping the part worn chain, repeating the process when the second chain got to the .5 wear limit.
After that it was a matter of swapping back on part worn chains that had been taken off. The last part worn chain I put on made it through the Winter but broke on a ride on Friday the 15th of March. That told me it was time to change everything and that was done on Friday the 17th of March, with new Cassette, chain ring, chain, and jockey wheels, .as well as a thorough clean of the rear Mech. I have to admit that a new transmission feels very good.
My new rear wheel that I had built in October 2020 has been brilliant so far soaking up all the punishment I can throw at it as well as on occasion overloaded Panniers.
Also lasting very well is the Schwalbe Hans Dampf gravity 2.35 tyre, run tubeless and fitted on the 14th October 2021. I have been really impressed by it, very tough, good grip of road, and wearing surprisingly well.
Battery
Still the original 400Wh battery that came with the bike. I have been very pleasantly surprised my the longevity of the original battery.
On a recent ride to a friends house which is 70/80% off road with a lot of climbing including a long demanding climb which dominates the first half of the ride. Then at the end, after the last section of off road, there is a mile or so of road work to my friends house, and as I knew I could charge the battery when I got there I upped the assist to dispatch the remaining hills and blast along on the road at a good lick. By the time I reached my friends house I had ridden 15.1 miles and had just over half of my batteries capacity remaining according to my Yamaha display.
As I said last year, not quite the resilience it had when it was new. However the performance is certainly not collapsing at all.
Although the range you get out of any battery depends on a lot of variable factors I think that my assisted range is now around 35 to 40 miles.
Motor
This was the year that I started to feel a little bit of play beginning to developing when I flexed the chain ring. I spoke to Peter at Performance line bearings, who told me to keep an eye on it as play develops very slowly in the Yamaha motor where the bearings are much more robust than the Bosch motor of the same era.
I eventually bit the bullet and got my motor overhauled by Peter. I spoke to Peter on the phone and decided that I would take the motor down to him in person. The joys of being retired and having the time to do so.
Peter has an industrial unit in Fordingbridge in the new forest, so not that far for me to travel from Surrey. I fancied having a look around and Peter was happy to show me a very well equipped work shop with all the tools for refurbishing my motor.
While I was there he opened it up for us to have a look and he said I had judged the time to have it done just right. So a full overhaul and a few new bits was agreed.
The turnaround was pretty rapid. I dropped it off on Thursday the 27th of October and it was dispatched back to me the following Thursday the 3rd of November.
So this refurbished motor was actually my second motor, the one that was put in free of charge at the end of my first two years of ownership when the first motor developed play in its bearings. This second motor has lasted over 5 and a half years and been ridden 10,610 miles before its trip to Performance line bearings. It felt good as new once it was fitted back in the bike. From my experience I would highly recommend Peter and Performance Line Bearings.
Breakages
Probably in my case this should be called neglect, the parts that have given up the ghost because I have not kept an eye on them enough.
So on one snowy, wet and muddy but great fun ride my gear cable broke. This was probably not helped by a dirty gummed up partly seized rear mech.
On another, snowy again ride, my rear brake lever came back to the handle bars. That was a brake fluid leak at the handlebars and easily fixed with more brake fluid and a nipping up of of the nut that secures the brake line to the lever.
I broke a probably very worn out drive chain very recently on a ride on the 15th of March that led to a probably much needed transmission overhaul with a new cassette, chain ring, chain, and jockey wheels, as well as a thoroughly cleaned rear Mech on the 17th of March.
The cassette that was put on was the last of a batch of Cassettes I bought for £8.50 delivered from Amazon. I have bought a replacement, again of Amazon but this time for £21.19 delivered. I guess not too bad, certainly compared to the ones soundwave buys. I did however have a stoke of luck after coming across some high quality narrow wide chain rings in a sale that only cost £10 each. I stocked up on those.
Conclusion
Well over this year I have ridden in 41 degrees of heat and minus 4 degrees of cold. I have really enjoyed a new 30 mile minimum round trip to a friends house, that has allowed me to explore some new off road territory. I think in this next year I want to explore more off road areas, probably by incorporating a train journey into my trips. Will I wear out before the bike, I am beginning to think that is becoming ever more likely. Hopefully still lots of fun to be had.
