Here are a few thoughts re my recently purchased 905SE, compared to my 905e bought early last year.

 

Most of the issues I had with my 905e have been resolved in the SE:

 

1. The forks are good quality, adjustable and with lockout. The ride is vastly smoother than the 905e. The 905e felt a bit wobbly, presumably because the forks flexed because they were thinner. The 905SE feels really stable and handles well.

 

2. The handlebars are now black and they have an ingenious adjuster which allows one to change their position quickly and easily.

 

3. The spokes are thicker and I suspect they will be less prone to loosening

 

4. The head bearings and the bottom bracket bearings look better quality

 

5. The tyres are bigger, vastly better quality and with Schrader valves.

 

6. The bike now has 7 gears instead of 6. I'm not sure on the effectiveness of the gears at the moment, as I have not used it enough yet.

 

7. The derailleur mechanism is much better than the one on the 905e

 

8. The speedo on the bike is completely unfathomable and doesn't seem to indicate actual speed at all! I haven't sussed out the battery indicator yet...... anybody have any ideas?

 

9. The rear derailleur has a protective cage which stops it catching on things

 

10. The sprung seat post WORKS! It never did much on my 905e...in fact I don't think it worked at all. The seat post is smooth and really makes the ride better

 

11. The throttle twistgrip is loads better than the cheapo one that was on the 905e. It's a solid mechanism and nice to grip because of its shape.

 

12. The rear rack looks much better now, being black instead of silver.

 

13. The road mudguards (as opposed to the 'sports' ones also provided) are really effective and look nice. My 905e didn't have these road ones at all.

 

14. Whilst initially confusing, the switchgear is a lot better quality than the throttle on/off switch on the 905e

 

15. The bike I have has a sprung 'big bum' saddle (put on by Frank?) which is loads better than the one I had on the 905e

 

16. The pedals look a lot better and are much better quality than on the 905e

 

17. The front disc brake and rear v-brake works 100% better than on my 905e. Excellent performance.

 

18. Importantly, the rear wheel can now be removed easily because the power cable now has a connector block which can be unplugged to allow the wheel to be taken off (a nightmare on the 905e)

 

19. The ferrous nuts and bolts of the 905e are now stainless (I think) allen bolts (eg on the controller housing cover plate.

 

20. The front wheel is no longer 'quick release'. on my 905e, the threads stripped on the aluminium nut of the locking bolt. I wasn't riding it at the time. I believe there have been posts about the dangers of this type of wheel, so I think the fixed front wheel is much better,

 

Personally, I think the Wisper 905se is the loveliest looking electric bike I've ever seen. The 905e was great too but the SE is even better. It's sleek, with lovely sparkly black paintwork now. The lines are really graceful and my 905e never failed to have people admire it.

 

For some reason, the 905SE looks bigger to me. Is this my imagination, Wisper UK?

 

Overall, the 905SE is a huge improvement on the 905e. I would say, looking at it, that David has done what he said to me he'd do... improve the 905e and produce a bike superior to the 905e.

 

I'll report back later once I've used the bike a lot more......

 

Hi Jimmy

 

I hope you enjoy your German SE as I have mine. My problems however were not down to the bike or Germany and all now sorted thankfully.

I love this bike and when you get on and twist that throttle the front end of the bike rises up on the forks as if ready for action and it is! It just go's and I have now sussed out the buttons I think?

 

I haven't seen any listings lately from Germany but probably wasn't really looking to do international searches as I have mine already.

 

You will not be dissapointed and the guys in Germany are second to none with help etc.

 

I agree with you over the warranty thing which has been discussed in previous threads as a little worrying. However, up till now have been helped by guys on this forum to sort the problems, with the guys in Germany or sorted them myself and with help from my partner and son. Just think positive and things may not go wrong??

 

I didn't personally like the city mudguards and found I could fit the sports mudguards with the rack and they do the job.

 

The battery is so light you wouldn't need to hide this in a hedge, It is incredibly light!

 

The gearing is much better than my old Powabyke for comparison but you had the original SE so would be able to compare better.

I had my Powabyke on 6 all of the time and my pedalling stroke was like being in 2 where as this one it really does work efficiently.

 

The bike looks great too and gets loads of attention! It is a good looking bike with everything, well almost everthing matching in black.

I have however changed my orange wheel reflector's for white one's and my partner found a front reflector, which the bike did not come with and fitted that for me. Why does it not come with a front reflector? Not the end of the world though, lol!

 

Let me know how you go as a newbie to this bike myself, lol!

 

Regards

The jury is still out on the performance of my 905SE. My initial reaction is that it is not as fast, or as smooth, as my 905e.

 

I did about 20 miles today along the exact same route that I took the 905e. Two things were noticeable... even unrestricted, the throttle is definitely nowhere near as powerful and also the power delivery is jerky and not absolutely smooth like my 905e. The speedo is completely useless, by the way, inaccurate and unreadable. The battery indicator is similar.

 

I have e-mailed David Miall and asked what he thinks and whether the UK upgraded bike will be the same. Paradoxically, if I could, I would swap my 905SE motor and controller for those from a 905E if it resulted in the same perfomrance as my old 905E! I would do this swap because the rest of the bike is so much improved (especially the forks I keep harping on about) but I am finding the uneven power delivery in pedelec mode and the lacklustre throttle a bit irritating. One second, assistance is there, then it stops, kicks back, stops, kicks in.... it's a pain.

 

I suppose it's a bit ironic... the improved 905SE is improved in many respects but lacking in important aspects... just like the 905E was (re parts quality etc). I've asked David if I can buy a 905E controller, if that would make a difference, or p/ex my SE controller and motor or whatever.

 

If I could have my 905E performance in the 905SE bike, it would be my perfect electric bike, I reckon. The 905E had good power delivery but rubbish parts... the 905SE has great parts and inferior power delivery...

 

Hi Jimmy

 

Okay I have never owned an SE for comparison but are you sure you didn't knock something when you came off it on the black ice?

You said it went like the wind?

I have only found the power cut out on mine if the green button is in the "other Mode" pedal assist? I dunno, well the other one anyway.

Or if the battery is cold.

The throttle opens smoothly and delivers the power expected and no jerkiness and mine was stuck in on a journey too and from work one day last week!

Try messing about with the buttons again just to see Jimmy.

 

I know what you mean about the forks though, they are ace and rise up as you open the throttle.

 

Don't give up and give it another go

 

Regards
