26" wheels on the Agutta ?

[mitty]

Hello all, I was wondering what the pros and cons of having a 28" instead of a 26" wheel on the new Aguttu are ? I live in hilly cornwall and for a long time have been considering buying an electric bike to help pull the kids around (ages 6 and 4) in a double seated trailer or on a tag along set up. top speed is not a problem as the kids will be behind, so would it be best to try and get an aguttu with 26" wheels or regear or change wheels on the 28" bike or maybe do both ? any advice greatfully received M

P.S great news about sustran getting the lottery money

They only do the 28" wheel as far as I know, but there's no relevance in the wheel size anyway. The bikes are geared for the legal maximum assist speed of 15.5 mph regardless of wheelsize.

28" wheel do have a comfort advantage over bumps, and they also run more easily than a smaller size.

Anyway, the wheels cannot just be changed on a bike with V brakes, since the brake mounting stubs would then be in the wrong place.

If you decided you wanted a bike geared differently, it's just a matter of changing the rear sprocket at a cost of around £6. The Agattu could be changed from the 22 tooth rear sprocket to the largest available at 24 teeth, this lowering the gear slightly. It wouldn't be worth going any lower anyway, since low on the standard Agattu already permits cycling at standard or full power mode as slow as 4 mph, so virtually at the limit of balance anyway.

Thanks for the replys, so now we know there is a 26" version would there be any advantage in it over the 28" when it comes to pull kids up hill ?

thanks again M

Very unlikely as the the manufacturers will almost certainly have changed the gearing to compensate for the smaller wheel size.

No, as I said Mitty, the gearing on these bikes is for the legal maximum of 15.5 mph, so all the lower gears are correspondingly the same with regard to road speed and pulling power. The difference is that each wheelsize has a hub gear sprocket size to suit, so that both end up with the same performance.

The difference in the frame height where you attach the trailer will only be 1 inch, so not really making any difference there either, so it doesn't matter which you choose from a trailer point of view. A 28" wheel is slightly more comfortable on the road, since the larger the wheel, the better it irons out the bumps.
