How much is average annual maintenance of a mid-range electric bike?
I have a Cube ebike with a bosch system. I have had it for a little over a year and done 5000km on it.

The expenses have been replacing the regular bike parts. Over 5000km I have had to buy


2 chains
1 cassette + chain ring
6 pairs of brake pads
1 handle bar grips
2 tires
1 bottle of chain lube
1 inner tube


I have used this bike about 50% on road and 50% on mountain bike trails. Your tires and brake pads would last longer on just road usage although thin road bike tires have less rubber and wear out even faster. Work out how much these parts cost to replace on your bike and you will have somewhat of an idea on how much it costs to maintain. Also factor in if you will be doing repairs yourself or getting a store to do them.

The actual ebike parts are a little hard to price. None of them have broken for me and I don't expect them to break any time soon but if they did they are very expensive and non standard. The battery is probably the most likely to wear out and a 400Wh bosch battery costs something like $800AUD


  Also, do e-bike repairs usually get done same day?


Depends what it is and how busy the store is. Something like a puncture repair will usually be done same day but a full service will be booked in usually a week in advance (but still finished the day you drop it off)
