I'm just talking about a regular pedal bike, not a motored one.When I get to hills, I downshift and have my cadence meet the terrain, motor or not.If it's all done by a motor you have a "moped" not a motor assisted bicycle IMO.Lewiebike has a good point as well, I'm thinking the old Sturmey Archers, but if you didn't have them adjusted perfect on occasion they would go into netural AKA freewheel both directions, if you were standing and cranked you'd have to have superior balance not to fall off because of lack of pedal resistance.Lewiebike,... Coos Bay, very nice, I've spent time in Port Orford and there's nothing like mountains meet the sea, and sideways rain.If you have to manually shift its not automatic. Here in the USA many state's laws require an automatic transmission system. These laws even go as far as to say no manual clutching or manual shifting of engine driven gears by the operator. They say nothing about a fully automatic transmission system which shifts gears. Currently this is a legal loophole due to the way the laws are worded.
My concern would be that it doesn't index the positions of the gears so you might have problems with it jumping back and forth between gears at certain speeds. definitely not a precision solution and one that might kill your Nexus 3 gearhub.
All I was saying is, an auto shift on a pedal bike (without motor) is silly, intergrated with a motor is what you're talking about.From what I've read all the frictions and golden eagles are "motor assisted bikes" IC engines, not a moped.This whole site is about motor assisted bikes, most of which are IC, and that's what I was talking about.If you only pedal to start the thing it's a moped.Here in the USA some of our states define a moped and a motorized bicycle as the same thing. Others don't want any self built motorized bicycles on their roads at all. The laws vary greatly from state to state. Some allow what you're talking about motor assisted by means of electric motors but don't allow motorized bicycled which are powered by a combustion engine.
Of the states which allow combustion engines most want them to be under 50 cc. Large riders in mountainous regions are going to have to have gears. Unfortunately many of these states want an automatic transmission system. They even go as far to say no manual clutching or manual shifting of engine driven gears. The auto shifting is currently providing a legal loophole around this.
