Agattu Rear Dynamo light Fixing Tip - Pedelec Forums

Hi Guys,

My rear light failed on my agattu. I phoned 50cycles and they said i should try changing the batteries, for new rechargeable ones. This worked first time.

This sounds like a common problem for these lights. Mines ~7 months old (running on always on or sensor). Am i daft or shouldnt dynamo lights remove the need for this? Ah well, save you guys some angst if it happens to you.

The front lamp is, but some Agattus at least, including my test one, had a battery powered LED rear lamp.

Interesting, both my Agattus, the first from November 07, the other from April 08, have dynamo powered front and rear lights.

Both my lights on my Agattu are also dynamo powered. The rear light stays lit for 4 mins after cycling stopped - safety precaution, when stopped at traffic lights for example. Would this safety feature require a battery?
I've had my bike since Dec. I did'nt think the spec had changed?

I believe the standlight is part of the system Robert, no rechargeable batteries needed as far as I know, but I could be wrong. The Agattu I tested was an early one, probably made a month or two before yours.

No you are not wrong Flecc, the rear standlight is part of the system and contains no batteries, rechargeable or otherwise.

Definitely dynamo driven front and rear lights on my Tasman.

I love the standlight ability of the rear light to stay on for several minutes after the wheels stop turning, but I wonder why the front light does not do the same?

mmm i have the " Busch & Muller Selectra LED lamp". Its wired up like a dynamo, acts like a dynamo but contains batteries. I got my Agattu in March.

So either its masquerading as a dynamo, ie is only on when dynamo is on + 4 minutes or it is a dynamo, but the standlight is powered by the batteries and the whole circuit must be completed by the batteries.

I guess this was a frustration with my Agattu - not having a leaflet explaining the workings of the lights. both front and rear lights have a stay-on feature but the front light also has a 3 position switch. With these light nights, i've not got round to figuring the lights out fully, it would have been good for some details to be included with the bike. The stay-on facility must include a form of energy storage, either a small rechargeable or one of those capacative cells.
