Electric bike reliability.

    I'm currently trying to find a good electric bike and one thing I've no knowledge of is the quality of the motors and electrics

    Giant seem to have a nice system with the ridedash evo , but loads of people say they give trouble :(

    Bosch seem to be recommended by everyone

    Are they all the same quality or is there more lemons with certain brands ?

    18k km on my gen2 Bosch before it had to be rebuilt. Original battery is losing capacity now at 22k km. Needed a new battery loom which was 35euro. It has never stopped or stranded me despite it being hacked about and mile for mile has been a lot more reliable than the family car.

    Big source of issues for any ebike is water ingress - never powerhose them and be careful with the hose - much like a normal bike.

    what does rebuilding involve?

  • Registered Users Posts: 2,265 ✭✭✭ Ferris

    About £350 and sending it to a company in the UK called performance line bearings. They open the motor and replace everything as required - mostly bearings. Very good service actually and nice to deal with. I removed and refitted the motor which is easy if you're reasonably handy.

    There's a few bosch bikes that i like the look of,but Id say they have been in stock nearly a year.

    Would it be right to think the battery may get lazy the longer it sits idle ?

  • Registered Users Posts: 2,265 ✭✭✭ Ferris

    I haven’t noticed. Mine sat idle for a year while I drove to work. No noticeable degradation when I came to my senses and got it back on the bike. I think constant charging cycles has more of an effect tbh. I can’t complain as I’ve always charged both at home and in work.

    if you're putting a battery into storage, apparently it's best to store it about half charged; it's better for the battery life than storing it full or empty.

    Have a bike with a brose motor to try tomorrow , fingers crossed.

    Im trying hard to try as much as i can , which is pretty hard when there isn't much around.

    I have turned on bikes that are on display to see if they keep the bikes charged halfway, some shops have them at full and some empty , the good ones seem to be half full.

    I won't let the battery bother me now though , if i like a bike Im just going to get it.

    thanks for the info

    I know nothing about them really but just bought a Riverside 500e from Decathlon and it seems pretty cool, wind and hills are not a problem, I wanted it for a new job and much longer commute. Pity they max out at 25km/h though, but I think they're all like that.

    In Majorca last year... climbing up Sa Calobra, I passed a lad on an E-bike. the battery had died and he still had about 2k top climb to get to the top! He was not happy!

    As if getting a bike wasn't hard enough at the moment
