Battle of the TQ HPR/40/50/60

[kingrollo]

Scott with it's fast lane bike top spec is under 10kg - but with the less powerful HPR40.

Rumours the next pinarello e bikes will use the HPR 60.

Seems to be a split in the way of thinking - less power but a slightly lighter bike - or more power but a heavier bike overall.

I'm thinking more power will win the day.

Although not to the extreme of the Dolan e bike - which I believe is over 13kg - but a powerful polini motor 75nm

Thoughts ?

It depends on how you want to ride. If you expect rely on the motor a lot then more power & battery is better, but if you normally ride manually and just use the electrickery as an extra gear for the steep bits then weight might be a priority.

You need to take into account several things

1) when riding with no motor help - how much resistance does the motor provide
My has veery little - it is the Bosch Active Line
but I have heard that the more powerful version - Bosch Performance Line - gives a noticeable amount of resistance if you ride with the motor in "Off" mode

2) range - range is measured when riding in ideal condition - so no head wind and no climbs of any kind and a very flat surface
if you are going to be ridig on hills then you need to have an idea of what the range will be on the sort of terrain you will be riding on
and it is measured in the lowest assists mode (Eco on mine)
so you also need to have an idea what a higher assist mode will have on the range

In my experience - the battery is a LOT of the weight of the bike
and the higher the range the higher the weight - you are basically just adding more small batteries to the box that contains then and all the available batteries are pretty much the same - so more = heavier - lighter - less batteries and less range
The possibility of reducing the frame weight (etc) is not very great compared to the battery weight based on a reasonable start point

if you can work all that out then you will have a better idea of what you need/want

but the manufacturers do try to hide things behind woffle and technicalities
