Razor EcoSmart SUP: What Reddit Really Thinks

Did you consider lithium battery replacement options? They're more expensive, but SLA batteries really don't last very well. Consider the lifespan of lead. Keep track of how many charge cycles you get and your range. Then think that a smaller AH lithium battery will have better range, and more cycles. Lead batteries are rated on a 20h discharge, if you discharge faster the AH drops pretty quickly.

The larger the wheel, the more torque is required to turn that wheel which requires a larger motor and batteries. That's why 16-inch diameter wheeled scooters aren't speed demons — getting that size wheel to turn fast and maintain a higher speed means $$$. Large wheels give you stability and traction.

Avoid anything with lead acid batteries, that includes this one.

Yes, I have been looking at the lithium replacements and was tempted because they're so much lighter...but the cost made me change my mind!

I have a moral thing about lithium: the means of which are used to mine them, the pollution people irresponsibly cause in doing so, and the minimal knowledge still on how to dispose of spent lithium. My setup is outdated. Plan on a 72V setup soon — not for speed, but for a 100 mile road trip pulling a small handbuilt camper.

Also btw, you only get so many quick charges on LiFePO4s as well, just like SLA. You have to deep cycle charge them like you do any old battery, otherwise they will wear out just as quickly.

I got one for nearly free and I love it, but I'd probably be hard-pressed to shell out almost $500 for a new one. Pros: goes anywhere, seat is nice. Easy and fun to ride. Cons: It's built cheaply. Rear drum brake only. Cheap cup/cone bearing setup. Lead-acid batteries suck and have little range.

I have one. It's an older Razor model so very old tech. Brushed DC motor, noisy chain drive, and lead-acid batteries. I got mine used but I would never consider one for full price. There's a new version of the scooter with a brushless hub motor which will offer more efficiency and will be quieter, but still has crummy lead acid batteries.

I'd rather get an ebike than an eco smart TBH, very short range.

The ecosmart runs on 3 lead-acid batteries in series. I believe they're 7AH each. The easiest upgrade for range, is to just replace the batteries with the biggest 12v lead acid batteries that will fit. You will of course gain range, but the scooter will be heavier. Speed will be the same, more or less.

Charging lithium batteries requires a lithium specific charger. The stock charging port goes through the motor controller, so I bypassed that to use my own charger. Lithium batteries require some extra precautions when using in a retrofit situation, because although the stock motor controller tolerates the extra voltage, it does not have the low voltage protection that lithium packs require.

Very nicely done, but get rid of those stickers. I have one as well, and the rust is out of control.

I hope you bumped up to Lithium. I had some old 36v LiFePo4 batteries from previous scooters I tossed in for a short while, and you can get double the Ah for the same amount of space!

As long as the nominal voltage for the battery packs are the same you should be fine upgrading to higher AH, and of course that it fits.

This kind of scooter is pretty new, only started seeing these pop up last year. It'll be a while until they actually make higher power versions. They would definitely be suitable for high power — bigger wheels are way better for handling at speed and safer over bumps.

I've been wanting something like this for a while too. Closest thing I've found is a kick bike. Modding a motor/battery onto that shouldn't be terribly difficult but it's beyond my financial reach at the moment. With how new all the micro mobility things are, it's going to be very DIY for a while yet.

You're saying you need to just remove the tensioner completely to get the sprocket to fit with the stock chain? Is that the only modification needed?

I have two Currie 500 scooters that I rebuilt lately. The wiring runs are dumb — passing all the current through a SPDT switch? Ugh. Also why is the controller in the front not rear close to motor. I left my SO's stock except for new batteries. Mine got a few wiring mods.

Only thoughts are getting a 16 inch wheeled petrol scooter and converting it to electric. You could part out the electric scooter that is donating the battery and controller, motors etc. Would be interesting working out how to house the smaller electric motors into the hubs of the 16 inch wheels.

The Razor has no front brake and is therefore unsafe by definition. It also has SLA batteries, which are heavy garbage. It can be made into a pretty good scooter if you feel like DIYing a front mechanical brake and a LiIon or LFP battery, but right out of the box it's pretty shit - as all Razor stuff tends to be.

It looks like a nice platform as a base. If you could replace the band brake with disc and add a disc brake to the front, that's a good start. It'll probably never be a speed demon but it'll be a nice cruiser.

I really enjoy my razor Ecosmart SUP. Paid $50 bucks for it on offerup. Have spent about $250 on mods. Went with a 203mm disc brake using a threaded adaptor on the hub motor. The frame is already drilled for a caliper mount on both sides. Made a spacer for the deck approx 1.5" to use 5 - 9ah batteries and a 3000 watt sine wave controller in the deck.

You could actually upgrade very easily to a 36v or 48v battery, and if you go on AliExpress you can get a brushed motor like razors use really cheap. There are plenty of 48v 1000w brushed motors for under $75.

I could do 48v 18ah 13s5p battery with a 48v 1000w brushed motor and controller — do the whole thing for $250. Turning into a 30mph cruiser with probably over 25 miles range with an 18ah.

I pulled the trigger on a Razor Eco Smart SUP recently. My plan is to modify it using LiFePO4 SLA-style Replacements. 36v seems fine to me at 15 MPH. I've been 14 MPH on some scooters and it's plenty fast for my taste. The Lithium pack will increase the battery use time.

The stock controller works great on 12S Lithium packs. I have mine on a 12S (50V hot off charger) 8AH battery pack and it goes over 20mph with better hill climbing ability.

I have this particular scooter and it's an all around decent product but I have two main complaints. First is the limited range due to the type of batteries used. I rode up to the 711 this afternoon and by the time I got up the hill that connects our neighborhood to the main road I already got a low battery light.

I currently own both a razor ecosmart metro scooter and recently purchased a caroma P1 scooter. The ecosmart metro is slightly heavier than the P1 and from my experience doesn't have as much range given the sealed lead acid batteries vs the lithium ion batteries found in the P1. The P1 also features front and rear suspension which is something that the ecosmart does not.

When I first received mine I had to order a replacement fork before I could even assemble it because the tube on one side was bent slightly backwards and the wheel drop outs were also bent.

I do about 50 miles with my current batteries. I'm running 3 35AH solar storage batteries. They don't have a lithium option on the electricscooterparts.com site.

If you toss on the 1000w motor, I highly recommend a battery AH upgrade. Motor install requires some light drilling, and borrowing of two of the deck screws. Also note that you will have to remove the chain tensioner once doing the motor and sprocket mod, as the larger motor sprocket makes a super tight fit of everything.

I have the same bike. It had to sit in storage for a while and I am about to try it since having it not being charged for quite a while and I was concerned it wouldn't even charge, but it did. I'm already thinking about a battery replacement and how I can upgrade it or make it more efficient.

The battery box is about 6.5 inch wide by 13 inch long and 3 inch tall. I bought 12V 10Ah batteries to upgrade but they will not fit — the battery box has plastic ribs which keep the original batteries in place but prohibit a larger battery.

I would do more research into this model of scooter. I don't know much about that specific model but usually Razor is not very good. I think at the very minimum a Xiaomi M365 or a Segway kickscooter for build quality.

I am going to do this motor upgrade with my new scooter I got on hella discount. Thanks for sharing - so interesting!

Can you link the motor and sprocket? I have two of these and wouldn't mind upgrading one for fun. I plan on making a lithium pack for it.

Is buying three of these lithium batteries a drop in replacement for the three SLA batteries that come with the eco smart? I have an eco smart and have been looking at upgrading to lithium. It's all a bit over my head though.

If you're determined to keep using this frame, ditch those ancient SLA boat-anchors and get a LiIon or even better LiFePO4 battery in there. After that, theoretically nothing stops you fitting a 52V battery and controller and a brushless motor, for a serious performance boost.

I've actually done one more mod since this vid was taken, it cruises at a solid 35 now.

Lithium ion batteries are more dangerous as they're prone to exploding or even spontaneously igniting even when not charging or when the scooter is left on for long periods of time simply because the batteries tend to overheat rapidly.

Does any manufacturer make a premium scooter with 16 inch wheels?

Maybe 10 inch wheels are good enough, idk. Maybe there's no difference going over a pothole with 10 inch wheels vs 16 inch wheels. I just imagined it would be much safer as the wheel has a much lower chance of getting stuck thus faceplanting you immediately at a high velocity. I thought it would be a smoother ride.
