There has been a lot of dissatisfaction voiced recently about bikes being advertised but not available. It is not only 50 Cycles. I waited for about six months from announcement to the Wisper 905se becoming available. I feel sorry if there is anyone waiting for the step-through Wisper...

I've always had mixed feelings about cycle lanes. I have heard that they were invented by the Nazis in Germany in the thirties and made compulsory, to keep the roads clear of bikes. They were highly unpopular in Britain in the early days because the bicycle riding poor felt they were an...

I need a battery for my Tongxin-powered bike. I am pretty sure it will be NiMH. I need 36V and with a decent capacity - at least 10Ah. Mindful of Jeremy's recent experience, I want something that is good quality and proven. Doing a few searches, the ones that stand out are 1...

UPDATE - 19 October 2008 - Fixed it; see new post at the end for details! UPDATE - 21 February 2008 - the motor is not now working. I believe it is a controller problem but have not been able to investigate. I've also heard reports of others having both motor and controller problems so, as...

In the last week I have seen: Last night, a cyclist at my office who had, in addition red flashing lights on the back of his bike, a flashing blue one. I can only conclude he likes to pretend he is a police car! This morning, a chap on a mountain bike going along the Embankment wearing a...

I'm a bit mystified! Does anyone know if it is possible for an SLA battery to start spontaneously supplying high currents without them being demanded by an attached device? I bought a 36v charger for the SLA which I have been using as a test battery. On connecting the charger to my...

Is it normal to get water in tyres? I just changed mine and there was a couple of tablespoons worth of water inside each one. Never noticed that before. Frank

While trying to take the back wheel off my Wisper to change the tyre this morning I discovered a potentially serious problem. My bike has done only 100 miles but the rear dropouts which house the motor wheel are showing significant wear. This is obviously due to torque from the motor axle...

I see that Renaissance Bikes in Canada is now selling an Ezee motor kit. First time I'd seen these available; price is reasonable at CDN$1250 including a (lithium) battery. The description seems light on detail - not clear if there are any performance options available, what speed the motor...

Does anyone know what the type of connector / plug used on a Powabyke charger is called? It looks exactly like an RF plug on a coaxial television aerial cable, only the central pin is somewhat fatter. I'm trying to get a socket to run off this charger so need to be able to identify it...

I managed to get a trial on the long awaited Wisper 905SE yesterday. It's a nice looking bike, other than some monstrously large suspension forks on the front which look as over the top (in my opinion) as those on the Ezee Cadence. Thankfully they can be locked so need not interfere with...

What bike should I buy? It is predominantly for commuting. My journey is 12 miles each way, across mainly flat central and West London. I looked into buying a bike in May, but then I discovered my firm's Cycles for Work scheme, which only has a window in November for buying a bike. I...

Carl (or anyone else), My wife now has a Powacycle Windsor, which she is very pleased with. I'd like to upgrade the tyres. The front was no problem but the back looks a little complicated with the electric cable going in to the motor and little play in the cable. How do I disconnect it...

I was browsing the AtoB web site last night and saw that they have a new 5-star bike at the top of their rankings, the Gazelle Easy Glider. I don't know much about it other than their description. It's clearly a crank-mounted motor, drive through the gears, pedelec set-up in the manner of the...

I'm currently doing some work that invovled looking at price trends in stainless steel, of which nickel is a key additive. I came across historic price information for Nickel, which shows prices soaring in 2006 but declining from a peak around May this year by almost 50%. This gives some...

When I put my Lafree battery on to charge, after a few minutes it goes from the red light illuminated, meaning 'charging' to the slow blinking meaning 'fully charged' However the battery (which was fully discharged) is only showing 1 light, indicating it has hardly charged at all. Does...

I got a new bike yesterday! I managed to find a Lafree. The chap at Vita Electric, the dealer in Hampstead, was selling off his demonstration model, so I decided to buy it and took delivery yesterday. It performed well on the ride home. Battery handled the c.10 mile trip with plenty left...

They are available for £20 per tyre from Spa Cycles, the best price I found after a bit of searching (post free if order is over £50). Having read about them on this site, I ordered a pair for my non-electric bike, which had a puncture needing attention. I fitted them and pumped up to about...

I had been intending to buy a Forte in November, which is the window when I can use my employer's Cycle to Work scheme. I have to say I'm not so sure now. I've just read the review that A to B has done of the Forte (& Forza) in the latest edition. I found it a little disappointing. If you...
