I've tried various ways with Bosch and never seen a spark, but nor do I know what is best for the system, or even if it makes any difference.If I try to connect the charger to the battery in-situ with it switched off, I get a spark. If the battery is switched on, I don't.
They can argue as much as they like, the controller has capacitors in it. The moment you connect a live battery, the capacitors instantly charge. Any nitwit should be able to understand that he can't see any spark if the connection is shrouded at the time of connection.Owners of Bosch, and probably Yamaha, Steps and Impulse, bikes would give you an argument about that.
I've done about 10,000 miles on three Bosch bkes and have never seen a spark.
There's nothing to service. If yours is the old Emate with the battery behind the seat and cable brakes, then the brakes probably need adjusting and maybe check for loose spokes. That's not necessary on the later models with hydraulic brakes, which should go several thousand miles before the pads need changing. Any bike shop should be able to do that, though it's not exactly difficult to do it yourself.Hi my 2 year old oxygen MTB 16AH is going to be coming back out from its winter hibernation soon. I've not had it serviced yet by a bike shop and probably done 600-800 miles. I was wondering if any one had theirs back to Oxygen/Syebc for a service and what they thought of the cost and the work they did. Has any one used any one else for a service in the shef/rotherham area or do you all do your own. If you do it yourself what would you suggest needs doing. Towards the back end last year I wasn't really happy with how the gears were working and could never get the rear mech adjusted to index through the full range in both directions properly every time.
You're braver than me...Given the hard frost we had, I took the bike cross-country today. The bridleways were hard due to the frost. That was fine on the first stretch, where I was on relatively flat farm tracks, but once I got to the fields near Kenilworth, I hit rutted animal tracks. When I got to a bridge, I got off because of the very deep ruts.
The bike coped well enough, but it was out of its depth (as was I!) on such technical bits. The battery, however, really doesn't like sub-zero temperatures. I may have to nurse it on the way home tonight. I shall think hard about that 48V replacement...
