What an excellent concept. Looking at their web-site, it doesn't seem to be too heavy or bulky. The overall width looks to be only about the same as normal handlebars, so shouldn't adversely impact the manoeuvrability advantages of a bike either. Great conversion.

If it is manufactured in the Far East, would it be a Chinese Wisper?

I recently fitted a Woosh kit to my tandem: https://wooshbikes.co.uk/?hubkits#dwg22c-48v-kit My experience so far may be of use to you as the overall weights will be similar. See this thread for more details...

I too have recommended Woosh to other people because of their good reputation - which was borne out by my own experience in dealing with them. In several parts of their documentation, they are quite explicit in terms of advising that the kits are intended to be fitted by users with a very good...

Agreed - I've been pleasantly surprised by the power of the motor and the range of the battery. Woosh do seem to provide pretty honest and accurate information about their kits. Makes a nice change from some of the hopelessly optimistic claims you see bandied around!

What vfr400 has stated is correct in terms of how the PAS operates on my kit. My (12 magnet) PAS only needs a 90 degree rotation of the cranks to start working and it will keep the motor engaged even if the cranks are being rotated at a very slow rpm. I'm far from being an expert on e-bikes...

Hi Neil, I posted on the tandem club site too, but they make it quite difficult to upload images, so I also posted on here. The extra lever on the bars is an old-style MTB thumb-shifter and is used for the third (V-brake) on the back of the tandem. We don't go touring or carry heavy loads, so...

danfoto, that's great news, glad to hear it's doing the trick.

Excellent. I had just as much satisfaction in modifying my bike as I now do riding it. I bought a Woosh rear hub kit too and everything went together with a minimum of fuss. Enjoy the 'new' machine :)

My partner is also 60Kg and the standard spring at the minimum pre-load setting works fine for her. I couldn't get a soft spring a the time we bought our seatpost, but she's perfectly happy to keep using the standard spring as it takes away a lot of the road shock. The sleeve is just a...

You may be OK regarding the setback as most seatposts normally have some setback - the in-line seatposts are less common. As it happens, our tandem has an in-line post on the front and a Suntour NCX on the back so you may be able to see the difference:

sjpt - sounds like you had quite a 'road-train' going at some points in your tandeming career!

I'm not certain, but I think 7-8-9 speed MTB rear derailleurs / shifters are all interchangeable. From 10 speed upwards however, the cable pull ratio is different. I don't think a 9 speed shifter will index a 10 speed rear derailleur in the correct 'steps'. I have never tried it myself, but...

No - if your seatpost diameter is 27.2, that's the size of NCX you'd have to order, 31.6 is measurement of the seatpost diameter and is too big to fit her bike. The other measurement is the length of the seatpost - either 350mm or 400m sizes are available. We have a 27.2 x 400 on the back of...

Another endorsement of the Suntour SP 12 NCX. My partner (same age as your wife) has one on the back of our tandem and she wouldn't be without it. They are very good indeed for the money.

Excellent pictures Neil - love the basket on the front for your 'Navigator' :) I still have my titanium race bike, which is a lovely thing to ride, but I'm just not bendy enough to cope with a stretched out race position these days. Your tandem looks like a serious beast of burden - I can well...

Hi Neil – always good to hear of the experience of others, so thanks for the update on your own tandem conversion. We’re not experienced tandem riders either, although we’ve ridden solos for decades. Being able to call on the additional push from the motor is really excellent for tandems, but...

vfr400 - Thanks for the feedback. I didn't want to 'cook' the motor through ignorance or unintentional abuse. On some of our climbs, we often use level 1 assist only as anything more than that means that we don't put enough effort in ourselves. Cheers, Jodel (or CBR1100XX :) if you like).

Having covered about 200 miles now since the conversion, I thought I’d give an update. Bear in mind the hub-motor wheel is fitted to a tandem, so some of the comments below would probably not apply to a solo machine. Tandems are rather unusual machines and are generally higher maintenance than...

As far as I'm aware, the pull ratio on the 10 speed and above shifters is different to 9 speed and below. 10 speed shifters won't work perfectly with a 9 speed cassette. However, JTek make a lot of adapters which allow a mix and match of components. Have a look at their website and you should...
