As a long term user of Kalkhoff bikes, since 2008' and a combined mileage/reliabilty experience of the older Panasonic motor models of 32,000 ( thousand miles) they have proved practically faultless. Over that time, i have endlessly been an ambassador for the bikes and recommeded them to every head we turn when out on trips, we always seem to attract attention when 'parked' up.
HOWEVER, I have to say I have been completely UNDERWELHMED and CONCERNED about the long term oerformance we can expect by the new Tasman Impulse 2 we bought as a replacement. Too many concerns re reliability of motor (internal gears/clunking) and battery. Cycling along listening out for early signs of clunking does not make for relaxed cycling. My wife, for whom it was purchased, still prefers her old Panasonic Kalkhoff ProConnect, vintage 2008 and 12,000 miles on the click, and i cannot get her off it. Hence the new Tasman has only done a meagre 400 miles. I am very concious that the warranty time click is ticking, so trying to use it more to unearth any incipIent problems. In fact, it is the ONLY reason we go out on it, not fir the ride exoerience.
Would I buy am Impulse 2 motored replacement for my bikes Panasonic ProConnect and ProConnect S .
A CATEGORIC NO.
I would wait to see if the 2016 later generation Impulse (evo) motor is better, and does not generate reports of problems. Problem is, why keep tinkering with the motor if there isn't a inherent problem? Unless it development for development's sake in the search for even more torque, which most users don't want or need. Reliability is the key, which the Panasonic motors have been shown to have in SPADES.
Do I rue buying a the Tasman as a replacement YES
GOOD LUCK in making your choice
