What to do ?

[One_Box]

I have had my 2014 Ezee Sprint Primo for six months now and have used it throughout the winter.
It has been perfectly reliable and I have enjoyed riding it. I initially bought it for shopping journeys of about 9 miles but have now been riding it further for pleasure over a distance of 38 miles. As I have the 11A battery and the particular route involves 2100 ft climbing I am obliged to use a lot of human input to ensure I get home with at least one yellow on the battery readout with the ambient temperature at 6 DegC. The real problem comes down to only having a Shimano Nexus 3 speed hub.
Would it be possible to retrofit an 8 speed hub wheel plus the new controls and would it make financial sense ?
My second option is to sell the bike ( according to the flecc formula it should raise in the region of £530 ) and purchase An Ezee Sprint 8 with a 15A battery or go the whole hog and get a Kalkoff Tasman Classic Impulse 8 ( must be low step ).

I weigh 70 Kg ( still not got rid of the winter excess ), and am a reasonably fit 67 year old.

Any thoughts or suggestions would be gratefully received.

I doubt eight speeds would make much difference.

A second battery is the obvious answer. which would enable you to be more liberal with the assistance for the length of the journey.

Yes, a second or larger battery is the answer with your present bike, enabling you to use your powerful motor more liberally.

Before you commit to a Kalkhoff instead, bear in mind that a crank drive bike like that is very different from your hub motor one and can also entail a lot of work in climbing, possibly even more.

If your Primo has the eZee motor which i think it will have, that's more powerful than the Kalklhoff one, so for a given human input, your climb with the Kalkhoff would be slower.

Thanks guys, looks like a spare battery is the most cost effective option. Now all I have to do is lose 3 Kg to negate the weight of the extra battery.

Quite right as usual Flecc, the Primo does have the eZee motor as do all eZee bikes with the exception of the Quando.

It is often the case that when people go electric that they end riding further than they thought they would. For this reason, we try to advise people to opt for the largest capacity battery they can afford although I think this is understandably seen as an attempt increase our profit margin.

It sounds like a single 15 Ah battery would be the best choice for One_Box.

Recently we sold a 21Ah battery to an existing eZee owner, a couple of days later the same customer bought a new Torq with another 21Ah battery plus a 14Ah rack mounted battery for the same bike, they now have a massive total capacity of 56Ah.
