March 7, 20242 yr Moving the post disturbs the flow of the conversation, I'm sorry to say I dont like it Clearly it'll ignite flame wars if downvoters aren't anonymous, which I guess [mention=6303]Woosh[/mention] thought he was As the post went to the end of my feed You've probably got "Sort by votes" enabled. The raspberry one from Evans is only 2 kgs lighter but the weight is in a different place so I may go and test one of those I haven't read much about Specialized motors, they appear to make their own. Are they torque sensored? If so, as with the Fazuaaarrgghh! you might experience the same difficulty of torque from your legs not being sufficient to be recognised by the motor system? They have set the torque to the lowest setting and my legs still don't register I did wonder if there was a fault: If you're saying your bike jumped forward every second left pedal push, when every second left pedal push is applied with the same force at the first left pedal push, that sounds to me like it could be a fault of some sort... The Specialized motor looks kinda small too, might be another of those lightweight low assistance ebikes with small batteries for strong fit riders, similar to the Fauzuaaarrrgghh!? Best test one thoroughly on several hills methinks. Edited March 7, 20242 yr by guerney
March 7, 20242 yr Author What does this one look like motor wise? It's only 4kgs lighter, so not perfect https://www.onbike.co.uk/electric-bikes/orbea/optima-e50.html?fbclid=IwAR3aTpR5fhgPHu0k4KeS_6JkOzQCCuySYxZNszT1ZQJpsByMpxJeQYDC_Ls
March 7, 20242 yr Author The bike mechanics rode and and it was fab, they were quite confused; then one had been to the gym the day before and he was being careful with his knew and had exactly the same problems as me So it's me not the bike sadly
March 7, 20242 yr What does this one look like motor wise?

Simple, lightweight, understated. The only downside is the relatively expensive replacement battery and motor outside warranty (if you still can find them. The motor and battery are not common).
March 7, 20242 yr Nope, it was [mention=6303]Woosh[/mention]! it may be inconscious finger trouble but what did I do?
March 7, 20242 yr The crusa is too heavy and all the weight is at the back so it's unstable when I walk with it or load it on the train One quick comment based on a friend's experience, it may not apply to you. She tried a good bike with a frame battery and really enjoyed the test ride. As we were standing on the pavement after she'd tried it people needed to pass. She found it really hard to move the bike aside because the front was too heavy. Based on that she looked around and chose a step-through Gazelle Orange with hub gears and rear rack battery. Just as heavy and not so trendy, but (for her at least) much easier to manhandle when off the bike. ~~~ Asides. This was at https://www.thecyclecompany.co.uk/ (Shawford, near Winchester). They were extremely helpful. In particular, they allow sensible test rides (unlike almost all ebike LBSs) and have some short but testing hills just outside the door. In the end they weren't able to source the bike she decided on. She also found https://www.ebay.co.uk/sch/i.html?item=284354744987&rt=nc&_ssn=electricbikesbristol very helpful and allowed test rides (but not such good hills). They also could not supply the bike she liked. https://www.ebay.co.uk/itm/284354744987?itmmeta=01HRC3E74MBGKCQTDF7REBWS54
March 7, 20242 yr I plead not guilty. TESTING, TESTING..... -1 Oh, this is fun! Such power! I wonder if I can vote twice to cancel that out?
March 7, 20242 yr If you are able to include a trailer (main limitation I have found is does not go on a train easily), that solves the weight and balance issue for the bike, as you can offload as much weight as necessary. You gain lots of space, which makes touring much more relaxed. I put bulky but lightweight items such as sleeping bags and spare clothes in panniers, the rest in the trailer. Then your choice of bike can be less restricted: a rack battery is less weight than all your gear or shopping in a pair of 20l panniers, and so probably manageable. You might get on OK with a high torque mid-drive from Bosch, Shimano or Yamaha as they give much higher multiplication of rider input than the Fazua. You would be looking at Bosch PerformanceLine or even the CX, Shimano E6100 or even EP8. I don't know the Yamaha range. All of those would answer your hill climbing and load lugging needs - worst case is changing to a bigger cassette for lower bottom gear. BUT after the Fazua, you would have to verify by adequate test riding that they can do the job. You can do a quick test, which is put the bike in lowest gear and highest assist, and just ride away. My 60+ year old legs, otherwise in good order, do that without noticing any effort. But that is what you can only know yourself, by trying out various bikes. If torque sensor is an absolute no, then the simple choice is the chunkiest cadence sensored rear hub motor you can find and a good sized battery. That will do most things, but extreme hills or touring weight will be its limiting factor. Plenty of folk on here can flesh out that spec, and provide reassurance (or warning!) about capabilities. Otherwise what's left is cadence sensored mid-drive, where I have to plead lack of experience.
March 7, 20242 yr Author This is a review of the fazua motor https://granfondo-cycling.com/fazua-evation-review/ And this is a review of the motor I think the orbea I linked to before has ( https://www.onbike.co.uk/electric-bikes/orbea/optima-e50.html?fbclid=IwAR3aTpR5fhgPHu0k4KeS_6JkOzQCCuySYxZNszT1ZQJpsByMpxJeQYDC_Ls ) https://granfondo-cycling.com/ebikemotion-x35-m1-review/ Does it sound better for me?

No. Not enough help at low speeds, not a particularly strong hub motor, and your requirements include load lugging touring. Start with your needs, and put aside the relatively niche solutions (Fazua, ebikemotion) in favour of well established basic powerful simple generic equipment.
March 7, 20242 yr Forget any special or fancy motors or bikes , also forget about torque sensing bikes none are suiatble for riders with stamina , weak leg muscles or lung/copd/ breathing issues. The only real motor type is to keep it basic so a high torque hub motor and a throttle, a system that uses simple cadence pedal rotation as the PAS system. Current control controllers are best such as KT 's , others are speed controllers which can be a little abrupt .
March 7, 20242 yr The lighterweight bike you want really only exists with specialalist bikes for the fitter more able rider , typically these use small batteries (range extenders for the fit rider who needs a tiny bit of help) and smaller lighter motors . These motors will be often a torque multiplier system for those who can put in considerable effort. For the masses a normal bike weight will be 20kg - 25kg simply because of the 3 - 4kg motor used and often 3.5kg or so for a 10 -15ah (360 - 540wh) battery, any more ah will often mean a longer rrange battery and more weight.
March 7, 20242 yr So I really can't get what I need unless it's a special build? I think these things are a compromise. A longer range needs a bigger battery, which is heavier. Good hill climbing ability will tend to be a slightly heavier motor. Suspension adds weight. I think it is worth trying a couple more e-bikes for a demo. Low down , balanced weight between front and back is easier to manoeuver when you are pushing it. I think you might struggle to get something hugely better than the Woosh Crusa. Maybe there is stuff that is a bit lighter , with the battery mid mounted, but a lot of bikes will be step backwards for you
March 7, 20242 yr A Brompton or converted Brompton is about the lightest one may get for your needs. You want something to ride that is beyond your physical fitness/ health to ride, so a minimalist input bike is out of the question. As you have found, the Crusa is an ideal bike but too heavy biased to the rear. So you need to try a similar bike but a little better balanced as far as the battery positioning goes, weight wise you aren't really going to get a bike that much lighter thta will do what you want. A battery in the middle of the bike on the down tube is the best location. Edited March 7, 20242 yr by Nealh
March 7, 20242 yr Typically the lightest bike may be a small folder type around 20 - 22kg. The newer style designed Wisper Wyfarer step thru bikes are still a heavy 26 - 28 kg in weight. The Wisper Tailwinds are a bit lighter 21 kg - 22kg but they have a slightly different low crossbar design, a halfway bewteen a stepthru and crossbar. What you want doesn't really exist for your needs so one is going to have to ocompromiseon something, power control system of the Crusa works for you which is found on a lot of bikes , the new bike has the wrong power system for your needs so the more specalist type of bike is out. Weight is where you will have to compromise and accept it goes hand in hand with most bikes that will suit your needs because of the power you need and the simpler rideability of the PAS system.

March 7, 20242 yr I vaguely remember seeing a review of a gin x e-bikes that was a bit lighter, but don't really know anything about it
March 7, 20242 yr We tend to recommend the reliable brands ( often ones not familiar with public as they are specalist e bike brands only) these brands are amonsgt the oldest supplied brands available and with the great CS they are known for, but not main stream names that most people will have heard of. Typically Wisper and Woosh are two of those and they keep spares and are reliable. Once you venture into other brands that are a bit more niche then you will need the same type of service , often these niches are around for afew years then disappear or once they have your custom cna be hard to deal with or have the bike repaired due to lack of dealers or UK support.
March 7, 20242 yr The issue today vs 10 years go is that ebikes are being sold by every body and choosing the better bike for ones needs is getting harder . Typically Wipser and Woosh don't sell you just any old bike because that is the stock they have , they are better then that and will sell you the bike that most suits your needs as they have had many years of expertise in the game.
March 7, 20242 yr For a hub bike one should be looking at 48v , though Wisper have the new 43v bike which approx. give 18-20% more torque/power then 36v bikes. One could convert a lighter bike and use a BBS01 as guereny has done and use it tuned to max power so that you can pedal is easier or better still us eit with athrottle and ignore the illigality side of it. He uses a samll 20" wheel older type bike that gives high torque for his hills .
March 7, 20242 yr Author Yeah if I can't sort out a bike I can ride, it will be a bloody mobility scooter and I'm terrified of that
