Electric Bike?

[Sara_H]

I know this may well be considered to be a dirty word on this forum, BUT:

I live at the top of one of Sheffield's biggest hills. I'm no Lance Armstrong, and if I'm honest, I do often use the car instead of the bike as a result.

I don't mind so much when I'm going to work or for a day out - but for the purposes of just popping somewhere I can't face the thought of getting all hot, sweaty and red in the face.

Life would be so much easier withan electric bike.

I'm now seriously considering it when the next cycle to work scheme comes around.

All that said - I still ave the dawes sonoran - would it be easy to convert that to ellectric?

Any advice or recomendations?

One subtle but important distinction is whether the motor incorporates a freewheel or not. Any system that claims to regenerate or feed energy back into the battery won't, those are to be avoided unless you plan to use electric exclusively and never pedal.

Also, after a couple of years, your battery will lose capacity and need replacement - look for established electric bike sellers who should (hopefully) still be around in a few years time to sell you an identical replacment, or be able to replace the individual cells.

Thanks for replying - I still wish to pedal, just want some assistance up the hills.

What do you mean about the freewheel? sorry I'm not very technical!

Have a look at Electric Bike Magazine for some more info on the bikes and conversions on the market. It is Velovision's sister magazine .

Nothing wrong with going electric for the hills.
You can go with an electric wheel conversion on your regular bike or get a dedicated electric bike. Range and weight will be the biggest issue but if you are only using it to assist up hill then that won't matter too much but is dependent on how many hills.

There are two systems, one is throttle control (still legal in the uk) where you can operate a trigger and get powered travel and the the pedelec system here you only get power if you are spinning the cranks.
For hills the pedelec is probably fine as you can ofen dial in how much power you need/want to assist you.

Talk to Arch or bikepete as they are behind the Electric Bike magazine and have tested/reviewed quiet a few.

Stout steel forks or stays and dropouts are typically required on the axle you plan to fit the wheel motor onto, so the torque doesn't "round out" the dropouts or fatigue the tubes.
Your Dawes Sonoran sounds a teensy bit delicate for electric conversion.

The freewheel is just like the freewheel function on the rear cog that allows you to coast.
A motor without a freewheel will drag if power is off, it would be hard work to pedal it. A motor with a freewheel will not have any noticable drag when power is off, so if you plan to just use the motor on hills and actually pedal on the flatter bits, make sure you fit a system with a freewheel.

Have you thought of switching the chainset and cassette to have a 22 small chainwheel at the front and a 34 big cog at the rear?

Could also walk the bike up the hill

You'd be better off getting the legs and CV system in better shape. You'd soon think nothing of those hills.

I did this on my touring bike, now I can get up any hills just by sitting and spinning

I'm 24/34 on mine with no tour load.It is non impact can can be a bit boring on a long hill, so I have been know to eat a banana doing a ploddy 4mph.

As you live at the top of one of the biggest hills in Sheffield (I have never been there so I don't know how big that is!) then what is the problem with being a little out of breath? It is going to happen on the way home from wherever you have been so you can put your feet up and recover for a few minutes

Errrrmmmm......... because I don't want to. As you said, you don't live there so you don't know.

Dont mind if I'm home for the day, but it adds alot of time on to my journey, and I get hot and sweaty, so it stops me popping out and about.

If I had electric assist I'd be more likely to use the bike for doing lots of little errands and carrying shopping.

With respect, I've lived here for eight years, I still find it difficult, so I'm looking for a solution to suit me.
