This Fat-Tire E-Bike is the ULTIMATE Solution - Uncovering the Folding Ado A20F Beast 

Great review ordered this today on the back of it! Just to clarify some of your points..... If you want a throttle and 350watt motor order the international version, this is only legal in the UK and EU when on PRIVATE LAND. ADO will send the throttle seperate. If you want a EU or UK legal for UK roads and bike paths then order the EU version. EU or UK version can be unlocked, however it will never be able to use a throttle, apart from the cruise option (which is UK legal) and is around 3-5mph. You can however unlock the motor to 350watt to use for Pedal assist this will then make the bike illegal for UK use on roads or bike paths. I contacted ADO before ordering because I work in Driver training, so I cannot afford to get 6 points on my licence if stopped by the Police. Which is the UK penalty for having a E bike that goes exceeds 250 watt and 15mph assisted If you where to have a collision and cause harm, the bike may be taken away and tested to ensure it met UK law requirements. So Its not worth the risk unlocking IMO!

I love the sounds of the tires when you accelerate! It sounds so massive :D

Just ordered one of these, and this review has confirmed my research, great review and honest, cant wait to get it now!

Great review, very useful to include the spec comparison of the direct competitors. Must agree the torque sensor system feels much smoother than the commonly used speed sensors and combined with the high torque output this should be a pleasure to ride. Looks like a good bike that needs only small upgrades to be great

I bought an ado a20f for 30 pound non runner Put a new controller and 52v 18ah battery i had laying about put a twist throttle on it and bypassed the pas system use my phone for speedo and voltage reader for battery My top speed is 37 mph wich is more than enough its a funny little bike and is awsome fun

Wow. I like it a lot. Thanks for sharing your thoughts about this ebike😊

Shimano do not have many 7-speed derailleurs, especially for the higher end offerings.

It's a pity they haven't put here any better derailleur, especially since it's supposed to be off-road-friendly, as the Tourney they're using is lowest tier in the Shimano stack, has no clutch and the chain is flying up and down, simply dangerously, when actively tackling non-smooth surfaces... even if they wanted to keep BOM low for better profit margins, there are variants from the likes of L-Twoo or Tektro, relatively cheaper but still known brands, that offer chain protecting clutch design for a few bucks more. At this price point, a Deore with clutch design would've made sense if one would want to stick to Shimano. Or maybe SRAM Eagle? One extra niggle - pity it has cables routed below the frame instead of within... one more thing that might be cut or broken when those thick tyres fling the stones off-road. Or just an aesthetic aspect to keep them safely hidden out of harm's reach... Alternatively, it'd be truly funny if they made it with a belt drive instead of this crappy lowest tier Shimano derailleur... that and a proper water protection and this thing would've been far more fun-oriented... Or better yet, if they used this engine in the Air (Beast) with Air's wheels replaced by similar, maybe three-five blade/spoke, cast lightweight wheels. That'd be a blast at approx. 17-18 kilos and 60+Nm on tap in a foldable design! Instead, the Beast comes with subpar if not crap-tastic derailleur even though ADO wants to paint the picture of upmarket offerings and high quality components used differentiating it from the othet chinese competition... and the Air comes with a relatively weak engine that was possibly chosen for its lowest cost and weight combo feature in the components on offer matrix.

If it can't be unrestricted and doesn't come with a throttle then its not an upgrade to the A20F as that had both of those missing features.

I'm tempted to get the ADO A20F XE. There are other chinese (white label) e-bikes like DongC that go for half the price, but I'd rather spend for a better quality just for piece of mind that the battery won't explode under my butt... The good/bad thing about CE EU version is they have to limit the throttle to bare minimum so you have to pedal. For international version you can basically use the throttle like an E-motor bike, no pedalling required.

hi...i've noticed that these ebikes don't come with a charger and i was wondering if you knew of/could suggest which might be a good one for this bike? thanks, in advance...btw...your review helped me to decide which bike to get...thanks again...

Which do you prefer? Beast or Air 20?

Hi, we've had our Beasts for a few months and have covered 300kms on holiday now. Our bikes came with a throttle in the box, which I've installed and activated through the app for a hybrid drive. Its brilliant. Currently in hilly Portugal and on a mix of flat and steep hills with 16% and 20% gradients, using throttle and pedalling, we're easily achieving 1km per 1% charge. Only issue is that the fat tyres, give a higher ride height so its always out of the saddle to come to a halt. The added weight causes a few issues on restarts on a hill, especially for my wife. Ride quality is superb but front fork has poor rebound damping. If you can suggest a quality alternative and do a video on changing it, that would be fantastic. Regards, Paul Bassett

Hello, I have this bike for couple of days now & I'm really impressed. Brakes are perfect, fat toers are excellent. Weight is not that much for 100 kg strong guy like me ;) 120 km on one battery I don't know if it's true but on 1 supprt level with 1 setting on Shimano tube I got like 10 km distance for 8% of the battery (with sometimes 5 level support of handling hills & sometimes switching to higher at Shimano & support level). I think ot can distance for me 90 km at 1 assistance & 1 setting on Shimano (I think for 100 kg guys it's a perfect score . I got it extra free battery to for ordering now this boke (they got promor for it). So I got 180 km (with no holding back & driving city with easy). Charging battery for me from like 10% to 100% was for around 5 hours of charging. I did also a trip without a battery & only on Shimano support & ot was great experience. I didn't drive it bikes for 5 years & that was tough to handle at forst couple km for My legs but then got it everything set on 1 setting at shimano was perfect at start, then even 2 & 3 & at speeding I did even 6 setting & still feel comfortable! I was thinking about ADO A20 Air, but... To small battery for big guy like me. Only belt not Shimano system so that means you got only one setting on small toers & without energy in battery I bet it can be tough for legs to handle it. Only think great for me that stand out was this "self repair" tiers at Air bike, bit they are not fat, that means driving at woods will be difficult & not Shimano there. That means when battery is out of energy you are on though situation there. & I don't know if Air got this amortization for fron like Beast have & that make a job done, with compare with fat tires make it a huge difference. It feels very comfortable to drive around, all not flat surface don't feel rough for you as a driver. Also what I see it , very great on smaller tires is that it handke turing like a champ. On big tiers you cant be so comfortable with turning like in this bike. Also you feel safe on it, because it's not that small boke, and fat tiers make you feel steady. & Magic happen when you folding this peace of art. It take so much small space. You can take ot everywhere, train, bus, car, whatever you need. You dont take that much space & you still feel compact with it. One more this...did you imagine to drive woth make at the beach near see? Well...with this bike you got it, fat tiers, powerful motor & this excellent technology throttle sensor make ot huge difference. You can drive EVERYWHERE with it , no limits, only yours imagination (you can't do thinks like that woth Aor model , that is designed for city rides). So when you live neer woods, beach this bike open for you many possibilities that was not available before, trust me! ;) 5/5 stars from me!

Very nice review! Is Air 20 OK for me 105kg 187 cm? Will it help a bit on the 5degrees hills?

so...now that the bike's under way...a few other questions, if that's ok...one of the things i found attractive about the tech rx2 folding fat ebike was that it had a lock and alarm...is there anything that you know of available for the ADO beast...believe it or not, the stat on fatbike thefts in amsterdam is...are you sitting down? 90%...i read this today in a report in an article that spoke of insurance for fat bikes(which, again, if you have any suggestions i'd love to hear them...though, i'm guessing, since you don't live in the NL, would not be something you'd be in touch with). so...while i AM planning on looking for insurance later today(since it's after MN), i'd still rather avoid the experience of coming out of wherever i'd been and finding my bike gone... though a)i don't live in a'dam and b) didn't plan on ever bringing it there ANYways...my 'regular' folding bike does me fine there...still, i'd like to do my best to keep this bike...so i was wondering about the availability of these items...again. thanks...yours is a much appreciated service...and, while i've never subscribed to a site(aside from musicians), i am about to do that with yours after i finish this to give you SOMEthing back, at least...thanks again...

How tall are you for size reference?

It's a great e-bike. I really like it. A 48V version would be great.

Hope you can help me. I'm interested in an e-bike called FlySpace but I can't find where they are made I've looked all over the net no luck. It's the FlySpace 16 inch 350w motor found on Amazon Japan. If you have time? Thanks in advance, Edward in Osaka Japan

I'm a bike mechanic and my father in law has this bike shaped object. Too heavy for him to lift into car so pointless that it folds. The brakes are dangerously under powered for its extreme weight, have replaced with hydraulic. The chain rubs on the tyre when in lowest gear. Chain also rubs on the hub. Motor burned out after 1 summer of use. Company sent a used wheel as a replacement, had to get them to send another after a lot of back and fourth. New wheel arrived but the wheel nut was cross threaded. Disc was way overtightned on original wheel.

Great vid. Any chance you can answer a simple question that Ado are incapable of telling me! Do you know the length and diameter of the seatpost so I can see what suspension options might fit before I commit to buying bike. Thanks

Great - but ADO still refuse to include rear racks on any of their ebikes. I assume it's hard to find a low-cost (non-seatpost) rear rack that can be easily fitted to that rear frame. And why do no ebike testers/reviewers EVER criticize this lack of racks? For the Nth time: ebikes are not a serious form of transport without a rack to transport STUFF. Looking cool but stupid with a back-pack weighing on your shoulders + spine ain't the intelligent way to go in the real world.... Paul G

Can you please tell me what type pressure should be the tyre wall says inflation to Max 20psi

I'm trying to decide on this vs Engine Pro... it's a hard choice. I like the how much lighter this bike is (not that it's super light) but worried 350w isn't going to be enough for my 100kg weight. Concerns over the quality of Engwe, also. Any thoughts?

So the USA version is 350w and the engwee is 750 watt? Which is better overall

Thanks for the review. Now I'm just really in doubt whether I should choose ADO BEAST or Engine X, which I've also seen your review of. What would you recommend?

I ordered Engle engine x already. Do you think I was too early to order it before seeing this video? How much quality difference do you feel between engine x and this one?

Hi there! Nothing about warranty? How much is the warranty for electric motor or torque sensor?

Thinking about getting one, but i'm 192 tall, will that be a problem?

Please how do you remove the battery??

So at the end of the day, are you legally allright driving on Uk public roads with this bike?

You conveniently forgot about the Fiido m21 that has a 500w motor and a torque sensor.

Great review. 27kg is just too heavy to be a folding e-bike. I'm unsure who the target audience is for this bike.

lol eu only only allows 250 watts no throttle
