September 21, 20214 yr I wonder what happens to all the ebike batteries they do confiscate at airports? Do they end up selling for comparatively little in Police auctions, or are there gigantic warehouses full of confiscated batteries somwhere? Hope they're not simply thrown into landfills.
September 21, 20214 yr Author Likely a compatibility issue so you can't use a 3rd party battery . Yeah I was wondering what is passing through the 3rd connector? I was wondering if the 3 connector was due to the phase sensor being used directly from the batterie?
September 21, 20214 yr What about configuring everything to run off Hobbyking lipos? As soon as you get off the plane, you can order some. You get them very quickly and they don't cost muxh. If you have to get another plane, chuck them and buy some more.

Yeah could be an option as well. 21700 on kit would be about the same price, safer and still as fast though For now it seems there may be a problem with the qiroll battery 3 pin connectors... and the seller is taking forever to answer... so maybe it's bad they are taking so long when i m not even customer yet..

Sellers on many sites seem to be dropshippers, and might not know anything... apart from how to make quick fractions of a buck by dropshipping.
September 21, 20214 yr Author Sellers on many sites seem to be dropshippers, and might not know anything... apart from how to make quick fractions of a buck by dropshipping. i contacted the official qiroll site and got not much of an answer either: https://qirollshop.com/product/qre-muteb60/
September 21, 20214 yr i contacted the official qiroll site and got not much of an answer either: https://qirollshop.com/product/qre-muteb60/ Are you absolutely certain this is up to the job anyway? My 36v 250W bbs01b is great, and the minimum I'd accept, but at 24V, IMHO that Qiroll kit looks a little too puny for all but optically flat roads where all the air has been pumped out to reduce drag. Ok, that might be overegging it a bit, but you might be disappointed I think, depending on the relief of the country you visit. I think it'd stop on even moderate hills. That kit would work best on the moon, and might not be worth all the effort and stress in getting it through airport security.

However checking online reviews it doesn't seems too bad. This one did convince me it may be the kit to use: https://electricbikereview.com/forums/threads/review-qr-e-250w-electric-booster-bicycle-motor-and-b60i-and-b70-battery.35201/ He did say he managed to get 13mph on throttle only. Some other review apparently got 8-10mph on throttle only. So it looks sort of okay-ish? And currently I'm just cycling with a normal road bike I'm astonished how much smoother the ride is compared to a 20kg ebike with hub motor drag, even when its a 3kg small freewheel hub. This friction drive is 2kg total. Including battery and everything. Its 1/3rd of the BBS motor + battery kit. It may make a difference!

I can certainly see the appeal, small and light... just wish it was 36V or more. Mind you, at a higher voltage they'd likely need heavier batteries, which somewhat reduces it's small and light appeal. Well, I hope it works out... hope you'll report back when you've tried it out.

They have a 33v model one that is more powerful and also doing regen. It's not much heavier as well. Maybe 3kg total? I've been thinking to use it, but after consideration if I want something more powerful I shouldn't use a friction drive that isn t as efficient as a hub or chain drive

I've been thinking to use it, but after consideration if I want something more powerful I shouldn't use a friction drive that isn t as efficient as a hub or chain drive If I was dead set on buying this kit and they did a 33V version, I'd definitely go for the 33V!
September 21, 20214 yr My Revos friction drive is 24v/250w, I have been up some quite steep inclines in Mid Sx/Kent borders and not had any major issues. My Revos has no display, PAS or throttle but uses a led sensor that picks up the tooth count of the large rear sprocket to calculate speed and deliver the power. Like the Qiroll it only adds about 2.5kg inc the 208wh battery.

September 21, 20214 yr Of all the kits I have had BBS01 and various hubs front and rear because of the light weight and small mass, it is by far the easiest to ride over and above the 25km/h cut off and with none of the treacle ( dead weight mass) associated with other drives.

That does sound good, why not get one of those [mention=4766]cwah[/mention]? https://revolutionworks.com/
September 21, 20214 yr Price maybe. The Revos is UK designed and made. Yes, that is eye-watering in comparison... Saying British craftmanship is more expensive doesn't seem to apply to furniture makers, it surprised me to disover - I know a local firm who source cheap parts from all over the world, and weirdly the UK supply is sometimes just as cheap or cheaper than say Romania or Poland. But that's furniture...
September 21, 20214 yr I recall seeing the Revos people on Dragon's Den a while ago, and they rejected a suggestion from Peter Jones to source cheaper parts from Asia. They "Left with nothing".
September 21, 20214 yr Author Voltage isn't everything then. Maybe the OP will be fine with his initial choice of kit? Voltage is increased to reduce resistance. A low power kit can afford a much lower voltage. Whether the kit is 24v, 36v or 48v, all that matter is the wattage output. So usually I see this more as an incompatibility problem than anything else
September 21, 20214 yr Author That does sound good, why not get one of those [mention=4766]cwah[/mention]? https://revolutionworks.com/ I wouldn't mind buying from them. A bit annoying that I'm not in the UK anymore (i m in paris now) so I'd have to pay customs........ :/ I'd need to ask about the total weight of the kit excluding battery. It looks to be heavier than the qiroll... the quiroll motor is a wapping 520g! Also, they have 200wh battery. I know for sure this won't pass the airport. With the qiroll battery at 125wh, I still have some hope they will let me pass. But I'll send them an email and see if they have any suggestion for my travelling situation. Maybe I can get lucky we never know!
September 21, 20214 yr Author Looking at revolutionwork, the system looks a bit more bulky than qiroll. I expect it to be heavier although I don't know by how much... Also, it looks like I wouldn't be able to use my own batteries from their FAQs... "Can I use other battery packs with Revos other than the one's that you supply? Sorry no. The batteries are matched to the motor controller and the Revos won’t work with another battery and may even be damaged by it. Our batteries are excellent value for money and you can obtain another battery from us on its own if you want to" I still sent them a message... will see what they say
September 21, 20214 yr Maybe you could post the battery to yourself (virtual office or mailbox service in the next country) before you move, or ask someone to post the battery to your new address once you've moved? Bypass the airport confiscation risk. Get the postage insured etc. Edited September 21, 20214 yr by guerney

Cwah isn't a big guy. As far as ebikes are concerned, he doesn't need as much power as most of us.

Bypass the airport confiscation risk. Get the postage insured etc. Shipping battery is expensive and i may be hit by customs too. Not to mention the packaging requirement to keep the pack safe. My view is rather to keep a low cost battery (under £100) with me and buy a new pack if it gets confiscated
