Been a while since I rode four consecutive return trips to work (Monday to Thursday, 9th to 12th of March) on the Haibike.
I was rained on and cold on nearly every day at sometime or other. Thursday was mostly sunny and fine and then it got colder and darker tantalizingly close to work and there was a brief but vicious period of hail and rain necessitating breaking out the water proofs, that then stopped as suddenly as it had started. On one trip home on the road it was a deluge of water from start to finish.
More Suburban than Urban, encrusted mud, perfect for all the bearings!!
Even using my Winter cross country route to work the ground in places was saturated making progress difficult. One field I cross using a bridal path and with the motor off usually, required some judicious segments of eco to keep me moving over sections of water saturated ground. And of course there was slippery slimy mud that could not be avoided.
So the bike got filthy. There was no time to wash the bike between trips and the only maintenance was to add oil to the chain on arrival at work after my wet and muddy cross country ride in. I was not sure I would physically hold out for the week and was very tired on day two but rallied for the last two days and could feel my stamina returning.
Fresh chain oil on a muddy chain, not sure that will make it into Eddies forensic, "How to maintain your ebike"
How much wear I have added to my chain and rear cassette I do not want to think about. I covered 54 miles off road in four days. The chain and rear cassette have now managed 1290 miles. The bike performed faultlessly.
One change from normal that was forced on me by the front wheel bearings suddenly needing replacing was that I swapped the front wheel over from another non electric 650b mountain bike I own that is shod with Continental Cross King 2.2 Protection tyres. This front wheel and tyre proved a bit of a revelation combined with the less grippy but very hard wearing (6196 miles so far) Specialized Crossroads Armadillo 650B 27.6” Wired Clincher rear Tyre in 1.9” width.
Grippy wider front paired with narrower less grippy rear, surprisingly effective in challenging conditions.
Having a proper grippy mountain bike tyre on the front gave me oodles more grip in faster slippery muddy corners and everywhere else giving a real uplift in off road handling without the less off road orientated rear tyre compromising too much the better performance delivered at the front. This might be my perfect off road commuter bike combination, and it also worked well on the road.
Obviously if I had Continental tyres at both ends it would be even better but I am sure I would wear out a rear mountain bike tyre too quickly with the road work I need to do. Over these four days 40 miles was on the road to get me home after my shift and would quickly square off a mountain bike tyre at the rear, however on the front it should last a lot longer, and long enough to make the increase in off road performance worth it.
The nearly five year old battery resumed service just as it always has, using the same amount of its capacity on the 14 mile cross country route, around 30% of its 400Wh capacity and around 35% on the faster 10 mile road ride home using some higher middle assistance levels to climb steeper hills quicker and get me the 10 miles home in around 30 minutes.
I covered 94 miles in total and the bike has now managed 11,760. I am close to the end of my 5th year commuting and this year have done quite a lot less miles as I have not been required to go to my normal place of work. I will still have done about a thousand miles on the Haibike by the end of the year.
Also I now only use the Haibike when I can travel cross country to work. It is off road where a crank drive comes into its own and shows it marvelous capability. Just banging too and fro on the road wears out the drive train and I now use an old rear hub cadence sensor 2011 electric bike with an unrestricted throttle that I bought for £100 second hand instead and is a much better bike to ride on the road.
Whether all this will come to a premature end I do not know. I now have to leave my bike in a locker room, and other bikes are also left there and I can see that if a complaint is made we might be left with no where safe to leave them and that might be that.
I am so close to retiring in 18 months time, and have enjoyed so much riding to work, that it would be a real shame if it got kyboshed prematurely before I retire.
