Wisper 905 eco and sport differences

[ianripping]

OK so I have decided I want a wisper.
I like to the look of the Wisp 905 eco because of the cheaper price tag.

Will I miss any power on the eco compared to sport - to me it looks like the same motor and battery - the controller has 6 levels on the sport but only 3 on the eco.

Any ideas?

Hi, older Eco models had lower spec parts and standard forks. The latest Eco has been upgraded and is a higher spec with suspension forks. Looks to be very good value for money
Battery size also makes a big difference to price, so make sure you are comparing like for like
Worth dropping Wisper a line as their customer service is excellent and I'm sure they'll give you a full breakdown on the differences between the various models
If you are interested in second hand, there are a few on eBay at the mo
Good luck and happy wispering!

So by just talking to David at Wisper I now understand that the eco's speed is the same as the se upon being fully charged. As the battery is used over time, the se will outperform in both range and speed the eco.

The eco is lighter due to less kit on the bike and a lighter motor and battery (the motor on the eco is different from that on the se.

I think I am going to go for the eco since my commute is 10 miles at which point I can recharge during my working day.

What size battery does the Eco come with? It should easily be able to cope with your commute. Wisper guarantee the battery for two years as well, plus I believe if looked after it should last for a good few years after that albeit with a reduced range

Have fun!

The only thing holding me back now is the bike weight. I had s test ride of the 905se today and just felt s little heavy. Should I worry?

I would say it depends how you want to ride it. If you intend to use it with the motor switched on then the weight won't be a problem - although it does take a bit of effort to cycle much over the 15mph assist limit for any length of time.

However if you plan on riding it unassisted you do feel the weight and its hard work. I heard it once described as like riding an old fashioined Dutch roadster!

A friend in the UK has just asked me to supply him some phase and hall wire for his Wisper 905 eco, he suspects around 2011 model.

Not having heard of this bike before I asked him about the motor, trying to find out of it was geared or a DD hub.

Now having looked at pictures of it, it looks very much like a geared hub motor...but from the questiosn I asked him, he thought it must be a DD motor.
I asked him to spin the wheel and see if it rotated smoothly, or if there was any drag.

I'd have expected a geared motor to spin freely without any real drag, but his description wasw that there was drag and it must be a Direct Drive motor.

As I am not in the UK, i cant pop in and have a look.

So any one tell me if it is geared or a DD?

Better still, anyone in the UK, Exeter area that could have a look for me / him?

It's a 250w geared rear hub motor. You should only get resistance if you turn it backwards.

You can get the wires from BMSBattery or Greenbikekit. Why does he need it?

 

[NeilP]

Yes, that is what I thought. Well he says it works ok...and the wires are not broken or shorted, just with insulation damaged.Sounds a bit dodgy to me. He only sent me a really small picture, any one see if that is geared or a DD??looks suspiciously like DD to me.
