my Kettwiesel with front hub motor:


The first battery died last winter, I think it was a case of neglect and deep discharge. Not wanting to go guddling about in its innards I bought a bigger bottle battery (13Ah) which I’ve mounted forward of the seat... this makes for better weight distribution, the original one lived in the seat bag. The front wheel of the Kett is relatively lightly laden, paradoxically on really steep hills I have to back off on the power setting to avoid wheelspin but it will handle most “normal” hills (up to B road standards) without a hiccup.

I did think about mid drive, but from what I could see it would inevitably mean that something or other would be fouled if it would even fit the frame shape. I’d also lose the breadth of gearing and wanted to retain the ability to ride without assist. As it is with the two rear wheels human powered via a differential, I have a three wheel drive machine!

Unpowered the Kett is a steady but not quick performer, e-assist has made it much more comparable to my faster machine.

Lighted small Ebob.jpg

A few years ago we were kindly loaned a Raleigh BOB, an aluminium-framed 26" wheel MTB-style bike. At the time it was so much lighter than anything my wife had ever ridden, and meant both of us were now taking bikes on holidays, and using them for pub outings - evenings AND sunday roasts...... We ended up buying two more for our daughters (a standard BOB and an "S" small-frame version), because their light-ish frame and straightforward mechanics meant I could learn how to service and repair.

With the children getting older and moving to road bikes, two of the BOBs have languished in the shed for the last couple of years. Additionally, my wife has not been keen to use hers to do long-ish rides, owing to pain in one knee on exertion.

Above is a spare BOB conversion (I sold the "S" in the summer, new rider apparently delighted with their new bike) using a throttle-based 48v TSDZ2 kit. I fitted AXA and B&M front and rear lights, and a 14Ah HL battery to the rear rack. I'm making a cover for that, to keep the rain off, but that should still allow panniers to be clipped on either side. I think provided they aren't fully loaded (normally it's just waterproofs), we'll have no problem. Repair kit on one side, stay-dry pannier on the other. Lights on and off via the VLCD5 controller. Throttle option recommended by Woosh in Southend, so my wife can have the option of not pedalling if the knee starts to play up. Fantastic !
