Thanks, may be interesting. Can you point me to a website etc for this kit? The Woosh systems don't seem to have change much in the last 5 years. BTW, one thing I don't like about kit based systems is the plethora of untidy wires that end up all over the bike.

Thanks for feedback. More questions than answers! I'll try to explain. I've tried that; I converted a Dawes Galaxy with a Whoosh kit a few years ago. I didn't like the weight of the whole system, and I didn't like the poor power control system (although that has maybe improved over the years?). I'm aftera lightweight bike, no more than 14g or so. Bikes that are too heavy don't handle as well on the road, and are more difficult (for an oldie like me) to carry up steps, load into a train, etc I'm not into modifying systems like this: (a) it would invalidate any guarantee (b) it would increase the risk of fires I have tried two Fazua systems. I don't like clunkiness of the clutch engaging and disengaging. The battery/motor assembly is heavy to remove - my partner broke her toe when it dropped onto her foot while removing it from her bike. A 6m mains lead would be a lot of extra weight while touring! and I won't leave my bike outside a B&B overnight

I've been exploring the possibilities of using a range extender for touring purposes. I don't generally need an extender for day rides; tThis would be to allow a recharge when it's not possible to get the whole bike to a charge point at a B&B, so that I can continue riding the next day. I have so far investigated three types of system: Bosch 'powermore' system. As far as I can tell this system will run down both batteries (main and extender) at the same rate. So if (at the end of a day's riding) both batteries are at 50%, it's only possible to add another 50% to the extender. You start the next day with 50% of main and 100% of extender. Not ideal, especially if day 2's B&B doesn't allow charging either. Specialised Creo range extender. This appears to have two modes; you can switch between using the extender first, or using them both together (as per the Bosch system). Using the extender first means that it will be at 0% at the days' end, and the main battery will be at more than 50%, - so you can add more charge to the extender and start the next day in a better state of charge overall. One drawback of this system, though, is that you need to use the app to switch modes, and if left on 'extender first' mode the bike won't be powered at all when the extender runs out. So any problem getting the app to talk to the bike mid-ride would be a bit of a disaster. Mahle X35 system ; the range extender for this will charge the main battery as it runs down (it doesn't power the bike directly), so it will by default run down first and therefore can be recharged fully at the B&B. This seems to be a similar method for the newer Mahle systems (X20). Clearly one solution for the 'charging at B&B' scenario is to use a removable battery like the Fazua system. I have tried this and wasn't very happy for various reasons which is why I'm considering a new bike. Can anyone confirm any of the above, or offer any other thoughts , or systems I haven't noted? Thanks

3 weeks later, I finally found a bike shop who could look at this and fix it. Turns out that the bottom bracket and motor fixing screws needed tightening. First two shops (both supposedly Fazua dealers) would only work on bikes that they have sold. Third (my LBS) didn't have the Fazua diagnostic tools. I'm glad it's now fixed but my experience worries me about touring again with an e-Bike. Luckily the problem happened on the last day of a tour; what if it happened earlier and I couldn't find anywhere to fix it?

Yes. Same hills, same day, same rider. And if indeed one battery was 'knackered', why would the problem persist when I put a 'good' battery into the problem bike? And if it was a knackered battery, I would expect the problem to be worse when it was at a low charge. But it isn't. The problem is the same if the battery is showing 5 LEDS or just one.

I've rechecked and recleaned all the connections that are visible. The problem still hasn't gone away. I'm disinclined to undo parts that aren't supposed to be undone by users, so I'm going to contact a dealer. What I've noticed more and more, though, is that the problem is connected with the amount of torque required on the motor, rather than vibration. I can ride over very bumpy roads on lesser slopes with no issues, but as soon as the gradient increases (on a smooth road) the problem returns. This suggests to me that it isn't just a loose or dirty connection.

No, the other bikes rides perfectly after the swap - so it doesn't appear to be a battery issue.

I thought you might be right at first - particularly as the problem seems worse when I put a bigger load on the motor (i.e. higher gear / more torque for the same hill). But if it was the battery, I'd be very disappointed after 3000 miles - after all, a EV car battery is expected to last up to 100k miles! Anyway, my partner also has a Fazua-equipped bike and I have now swapped over the batteries. The problem stays with the bike, not with the battery. So is it something to do with the torque sensor, maybe? Unfortunately I can't swap out the whole motor/battery assembly, it's a slightly different fitting on each bike.

I have a 2-year-old gravel bike fitted with a Fazua Ride 50 system. It's been great but recently (after about 3000 miles) it has developed a fault. While riding, the top LED turns red, and power cuts out. It will return after a few seconds, then repeat. I've looked at the Fazua docs which say this: I have cleaned the electrical connections twice now (the second time with a toothbrush and alcohol cleaner) but the problem persists. Anyone else had this issue? Thanks
