Hi all, it is a long time since I have been on this forum. I mainly ride a non-electric bike these days, short trips to shops, etc., but still take my ancient Lafree Twist Lite, with external lithium battery, out for an occasional spin. Anyway, I was having a clear out and found the charger for...

On my way in to work this morning my beloved Giant Lafree Twist Lite snapped in two. It is the step-through model and the frame broke at the bottom. I was late for work as usual, going up hill at about 13-14mph, on the south side of Southwark Bridge. Naturally I hit the road quite hard...

I have just noticed that the 2012 Kalkhoff models all seem to specify 36V now with either 12Ah or 14Ah batteries. e.g. Kalkhoff : 2012 Has anyone seen any details or announcements about this? Or what other changes the new Panasonic unit might deliver? I would hope that the existing 26V...

The battery on my Giant Lafree Twist Lite has started to wobble about. It seems loose at the top. It is also hard to push into place. I have started to open the lock with the key, push the battery into place and then lock it in place. Perhaps I should always have done this. Has anyone else come...

My $99 battery has arrived from BMSBattery. It is dscribed as "Li-Ion NiCoMn shrink tube electric bicycle battery pack. Included 2p7s 6665143 cells, 1pcs 10A continuous discharge current smart BMS." It comes with a 1.8A charger, with a 2 pin, probably American plug. I will cut this off in...

I am sure there must be people who have tried this. How much overvolting can a Giant Lafree take?

I am looking for some new rear panniers. My existing ones are about 8 years old and completely worn out. They came from Halfords and were quite cheap, but Halfords only seem to do them in a smaller size now. What I am looking for are panniers that are very quick to clip on and off a rear rack. I...

Does anyone know the frame size of the 705SE? Cannot seem to find it on the Wisper site or this forum.

I had a problem with my new Technium Privilege the day before yesterday. The gear cable appeared to lengthen so that all the gears slipped down by 2. 7 became 5, 6 became 4, etc. all the way down so that the first 3 gears were all the same. I had assumed that something had happened at the hub...

I am considering relegating my old but excellent Giant Lafree Twist to Spare Bike status and upgrading to a new Kalkhoff or similar Panasonic system. My general riding style is "In A Hurry". I am invariably late for work so do not want to hang around. I also get enormous grief for getting home...

I am considering a budget electric folder and have come across Sunlova, which have a UK web site (sunlova.com) and sell bikes on ebay. Ebay responses seem good. Has anyone any experience of this company and its products? This is the bike I am considering: 20"New Aluminium Electric Folding...

My Giant Lafree is showing signs of age. The bike has done about 15 to 18 thousand miles over the last 6 years. Just took the bike in for a service as the chain is not running smoothly. I have been told that the front sprocket is showing a lot of wear. The bike shop is not sure what the part is...

I am investigating options for replacing the NiMH cells in my Giant Lafree batteries. I have worked out that I can fit 4 12V sub-C packs (e.g. like those available here component-shop) inside the case in a 2s2p arrangement. Has anyone tried this? If I do this with fresh identical packs...
