I’ve just shown how little I know about eBikes, so the Yamaha has assist more like an e mountain bike, I still think they could have avoided that big bolt on battery look, just look at some off road ebikes now, they look so much better eg Trek Powerfly and the Cube range. This to me just looks like early days ebike design.
In a nutshell, yes that washabi does have the same power as my current cube ebike - 50nm of torque, 250w motor, 500wh battery....
the ribble and the orbea are different altogether in that it has a rear hub motor, 250w, 40nm torque, but only 250wh battery.....but is a lot lighter at around 14kgs compared to the 21kgs of my cube and is easier to pedal unassisted as its cranks are just standard road ones.
there a lots of different options out there now in road design ebikes from the likes of cannondale, cube, orbea, pinarrelo, colnago, raliegh...that all have a different idea of what an E-road bike should be capable of......for me all i did was buy the cube emtb, switch the wheels and tyres to lighter and slicker, removed suspension forks and added MTB carbon forks and switched out the 9spd runing gear, for 11spd di2 and now i have exactly what i want for commuting and pleasure...
i then bought the same cube emtb as a 2nd bike and kept it all standard, for doing muddy towpaths, winter etc etc....i now have the best of both worlds available within the man cave
