First video off-road/climbing a hill:
your drive-train is destroyed because you do not pedal and most likely do not start out in a low gear, what do you expect?
It is interesting to me that Grin seems to promote the K.I.S.S. principle as well (one single powerful motor/control) when referring to the popular CAT trikes which I seem to remember as being much lighter recumbent tadpoles.I'm kind of hoping that I can wear out the OEM motor just to see what a Grin would do for this trike...yet I'll probably yank them both out of simple curiosity long before that happens...

Dual Motor Drives - Learn
Dual Motor and Multi-Motor drive systems allow you to get more power and torque than is available with a single motor. But they are also more complex to setup and wire.ebikes.ca
You are completely wrong about that. Building a mid drive ebike ups the ante on the required competence of the builder. When someone not up to the task decides to build one anyway, the incompetent builder promptly blames the equipment instead of looking in the mirror and taking responsibility for their mistakes (or even understanding that they made any).A high power mid-drive destroys chains and sprockets in no time that need to be replaced regularly.
You are just as bad as the person who started this thread (there's a reason he's mostly just talking to himself on this forum... you are new and missed the previous gushing over a different 'groundbreaking' trike).Fat tires are for mentally retarded people like you.
Not a whole lot of experience talking here. Mostly parroting back what you have read other people say on the internet, I'd wager. First of all, sure the early fat bikes came out of Anchorage, but they simultaneously were developed by a different group in the deserts of the Southwest, where they perform extremely well in sand. Additionally, if you ride overland (as in there is no trail, so not even singletrack) your vaunted 2.5" tires will go next to nowhere, while my fat tires will roll right over stuff.The origins of fat tires originated in A laska for riding on snow and ice, they are good for nothing else.
Not meaningfully. Especially if you match your air pressure to your terrain.Massive unnecessary weight drains batteries.
This is nonsense. First of all, a fat bike as a bicycle when in its element is about overcoming terrain in forest, sand and snow. Speed is a non issue and you are missing the point of the platform if you think speed is a driving factor in using them... but on the other hand, when was the last time you saw a motorcycle with 700x20C tires? There's a reason for fat tires on pavement and thats compliance and stability at speed. I put many thousands of miles (about 12000 across three bikes) on pedaled 28-32 mph bikes with fat tires. Hit potholes at 28 mph on a ride you are making for transportation (i.e. serious use not recreation) day in and day out and you will have a better understanding of the importance of fat tire wheels' utility and reliability.Slow to accelerate and stop with all that mass.....worthless compared to a 2.5 tire with quality suspension.
A tough guy running his mouth on the internet... Wow thats new.Guys like you are clueless in regards to the crappy knock off bikes you buy from some sketchy company that rips people off . Gosh , fat tires are SO awesome, all the pro riders use them. I hope I get banned ,to painful to deal with morons like you ,kiss my ass , you know nothing about high performance bikes, I do.....,I race bikes and motorcycles and am very good at it......so there, take that.....pussie
You are completely wrong about that. Building a mid drive ebike ups the ante on the required competence of the builder.
,.. Also a mid drive is MUCH much more energy efficient.
,.. A mid by comparison gets downshifted, and spins merrily away on lower power levels, using its power to move the bike not heat the motor casing.
Yes its supposed to do that. Your contention was that doing that was a bad thing for the chain's longevity. But it isn't.When compared to a hub drive, a mid drive puts all the motor power through the chain and sprockets.
Even if you did pedal you would have next to no power going thru your drivetrain, since a hub motor powers thru the axle. Drivetrains on DTC hub motor ebikes tend to be junk. Its a corner the manufacturer can cut because they can. The motor doesn't need it, and the rider won't stress it much even if they like to pedal. You are showing this poor quality to us up close and personal in the other thread where we see your freewheel is a $2 Temu knockoff of a Shimano product that - even when its genuine - only costs about $18.I don't pedal, so I have no power going through my drive line, so it will last forever unless it rusts out.![]()
Yeah its obvious that the product is not particularly well thought out.The MeetOne trike is using a hub motor as a mid drive motor mounted to the frame, but it only has one gear, so the efficiency can't be corrected by changing gears.
Your contention was that doing that was a bad thing for the chain's longevity. But it isn't.
Looks like a kart chain (google "219H") and yes that should last forever. But thats a custom solution that has no bearing on a mid drive bike that is made to have gears to run thru.Well, I did post a picture from the video where it shows the chain, and it's a heavy-duty chain from a motorcycle or something?
Not regular attention. But using a geared hub motor like they do on a big heavy trike is absolutely the way you would stress those nylon planetary gears so they are more likely to strip. USUALLY to strip gears on a Bafang G060 fat motor, the people who suffered the problem had both overvolted the motor (to 52v or even 60v) and on top of that used a controller upgrade that pumped the amps up to 35. That was on a 2-wheeler. Its not difficult to see how a big heavy trike with lower power but way more weight could cause elevated stress on the motor's internal gears so they can strip. The second motor will help alleviate that risk however. So... roll the dice it may survive just fine, or not. You'll know when they goI guess that if it's a geared hub motor (which is does look like), then the nylon gears inside may need some regular attention?
Nah. DD motors have peak torque at around 45 Nm for this quality level AND given the amount of space available. The only way you can get decent torque without going to an enormous motor is to go geared hub. It just makes sense to do geared hubs if you are trying to build something like this (it makes a whole lot more sense to do a mid in the back and a geared hub in the front but thats more money). My cargo bikes and my adventure bike do this mid+geared hub solution. They are unstoppable over terrible terrain, and never need maintenance.It might be a direct drive hub motor that uses the sprockets for gearing instead?
...big heavy trike...
(m@robertson) Yeah it's obvious that the product is not particularly well thought out.The MeetOne trike is using a hub motor as a mid drive motor mounted to the frame, but it only has one gear, so the efficiency can't be corrected by changing gears.
The beefiness of the overall build is directly related to the weight of the machine which nowhere resembles a golf cart (my other hobby is UTVs or glorified golf carts with turbochargers).211 lbs, apparently.Thats impressive! Basically a golf kart built with bike components.
It is always a risk and I don't recommend anyone taking it who should not. I have never had a relationship with any company up here beyond calling them as I see them in terms of features that I like. But one person (period) out there on YouTube who even actually has one of these is admittedly about as risky a proposition as it gets. My raw excitement versus common sense should be called out here and I'm glad that you did for the sake of everyone else.even a cheap full suspension setup made a believer out of me,the last bout of stenosis from hell has caused me to reset a lot of things I used to believe in first one being not 34 no more( double that) and its not going to get better on its own in a week like it used to[mans gotta know his limitations] however this thread has given me ideas Dash brings up several salient points,dual motor good idea,full suspension good idea,enough weight to keep it planted-however I hope he gets his trike and doesn't suffer the "sonders" syndrome and find out this whole thing was a scam( believe me it happens,some fly by nights disappear never to bee seen seen ago with the lucre.
It's 6061 aluminum yet something to keep in mind if you unbolt the two halves and modify it.do like the adjustibility hope its a steel frame.
