Thanks, that's exactly the step down converter I've had my eye on. Unfortunately I think my problem is going to come from the solar charger... I have asked photonic universe to recommend me a solar charger which is capable of charging a 36v li-ion battery. The only one that they supply is the...

Hi Tony, loving the Aikema kit, BTW. Though not put many miles on it as I commuted once, then Covid has got me working from home ever since. Have cycled up several mountain passes with 20kg of toddler on the back though which is much more fun - especially with no cars about. I'm not sure that...

Yes, interesting point about restricting charge on Li-ion car batteries. I did wonder why my battery was rated for 800 cycles whereas cars manage many more. I have a 24kWh Nissan Leaf. The actual capacity of the battery is 22kWh limited by the BMS. It has been recharged several thousand...

Ha ha, I do hear ya. :D That was my plan at the beginning. But turns out an £80 100Ah battery can only utilise half it's capacity without being damage so has 50Ah@12v=600Wh, same as the bike battery. An £80 lead acid is only rated for 80 charge cycles, so might only last a year or two. My...

Hi tech minded people. I am converting a lwb boxer minibus into a motorhome and am considering using my ebike battery for the leisure battery. Tell me if you've done it/how you'd do it/if I'm crazy. It is primarily for running a 12v compressor fridge, which I am yet to buy, but will consume...

My Woosh Aikema rear hub kit arrived yesterday, and I fitted it last night after the kids were in bed. The kit was well packaged with good instructions and took under 2 hours to fit, taking my time with it. I had a brief test ride down my lane, which aleviated any fears that I had about...

cheers sjpt, I've read good things about the Schwalbe Marathon Plus and I'm pretty sure a 35 should fit as the almost identical FX7.2 has them fitted as standard. I have thought that the brakes might be a weak point if I plan to ride in all weather more often. Looking at photos of the Trek...

Hi everyone, Thanks for your advice. I decided to order the Woosh lightweight Aikema motor in a rear hub kit with the 17Ah battery, left pedal sensor. Will post some pics and thoughts after the build on my Trek Fx7.3. Any extra advice for commuter bike upgrades? I have a pair of SKS...

I notice Woosh are eligable for the cycle to work scheme. Mine is run by Sodexo - how much commission do they charge? Is it worth my while using it or will they cream off most of the savings?

It's funny that you recommend the bigger battery as I came to a similar conclusion chewing over with my wife last night. Having bought a 5yo electric car we have done the calcs on range limitation based upon worst case scenario of a cold and windy winter day in in 3-5 years time, rather than on...

Having said that I didn't want to get into fabrication... I'm now thinking that an aluminium bottle could make a great sly sleeve for the Faro battery. Might be sneaky enough to stop my workmates from calling me a cheat when I get to work. :p The Faro battery looks quite long, What are...

I've got a Nissan Leaf, so know how unpleasant the last 20% can feel, though that's range anxiety rather than power limitation (never hit turtle mode yet thankfully). Still, the Faro battery would be fine for me, but haven't the time to start with fabrications really. Seems a shame to go for...

Yeah, thats my inclination too. I guess with lower energy demands, the range could be better than the bigger motor so further weight savings by using the smaller battery. I read your Faro review and it sounded like just the kind of bike I'm after. Hopefully my Trek conversion should feel very...

OK, I only weigh 11st and my bike is probably only ~12kg, and I'm not that unfit, I've just got chickenlegs and get put off by the hills and the weather round here. Which Woosh kit would you recommend? Given that I prefer the idea of a rear hub, for the reasons outlined at the top, it looks...

Thanks, that makes sense to me, but still confused about motor size and gearing, given that most motors quote 250W continous output, but obviously behave differently. I am keen to keep the weight down as much as I can, without sacrificing reliability/efficiency/rideability. It seems obvious...
