MX03 Power Assistance 1-5 Throttle Only! 

Thanks for the feedback, glad you find the videos useful, you’ll have fun with the bike 🚲😀

Picking it up, is it not being delivered?

@@RonWalkerCairngormGuides found a UK supplier, was worried about getting one from China.

@@amagnu100 I recently purchased the MX02s from a UK supplier next day delivery. But I coughed up 80 quid lol Yeah cheaper to pick it up, But I got too much going on and my budget was 1800 anyway - The bike was 1700 so job done.

@@danimayb didnt fancy the mx03 then.

@@amagnu100 The MX2 swung me in the end. I like the rack, and the battery is a cheaper to replace or a secondary one in future.

How did you mod it? Thanks

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-cD_q95707gE.html I have replace the controller with the kt25a and is much better that stock

Out of interest how many teeth has the original sprocket got and if you lived in a very hilly off-road area what would you change the sprocket to or would you add a two or three sprocket crank set?

@@RonWalkerCairngormGuides 42T on largest sprocket, the two smaller sprockets are not really required

Not had a problem when the battery is charged. Also as far as I know you can't recharge the battery by pedalling though by pedaling you'll obviously put less drain on the battery!

The bike's are now definitely geared for road use rather than off-road use which only becomes apparent once the ground becomes a lot steeper/more technical and you need more torque at lower revs. The bike's originally had 21 gears with 3 gear ratios on the crank but now has just one chainring with around 52/54 teeth which is good for speeds of over 30mph on the road. However on narrow trails it could do with lower gear ratios and I've now replaced the crank and chainring with a replaceable 38 tooth one which now makes going up the hill tracks here a lot easier but limits the top end to just over 20mph before ghost pedalling! I was originally going to get a 32 chainring and might try a 32 oval one but fear it would affect the top end to much without going for more gears and a new cassette! It's very easy to customise as all the bike parts are pretty standard.

@@RonWalkerCairngormGuides thanks a lot for your detailed answer. Much appreciated.

Leave it on until the charger turns green, allow at least 8 hours maybe more!

I think the stickers can be peeled of the black frame! Why do you ask?

@@RonWalkerCairngormGuides thanks! I’ve always preferred a cleaner look with my bikes so tend to peel off any logo stickers.

According to the website it’s 180 kg! See www.shengmilo-bikes.com/products/shengmilo-mx03-electric-bike-48v-1000w-for-adults-fat-tire-mountain-bike-with-xod-front-and-rear-hydraulic-brake-system

not yet but bought the green slime!

@@RonWalkerCairngormGuides Just about to slime my tubes, cant do any harm, and might help until I go full tubeless.

@@RonWalkerCairngormGuides Just tried the slime in mine, blocked the valve hole...... its going back.

A tip for ya Ron, remove the core, then I had to ream the valve hole there it enters the tube with a 2 mm drill bit. looking at the rims and tyres, I think tubeless is a non starter for mine.

@@amagnu100 obviously not as straight forward as it's made out to be! So have you knackered the inner tubes or can you still use them with the slime?

I mentioned it in the video when I changed the front crank ring!

Unless you are going downhill! ;-)

Not used it over the winter but still working despite the battery being left discharged over the summer or left fully charged for months over the winter when not used. I initially had problems with the battery connections but it’s a well known issue that’s been sorted in later models and easily avoided if you don’t use it continuously on throttle when going up hill! The newer models should be better though they don’t have the 4 inch fat tyres which are good for the off-road tracks here and some don’t have hydraulic brakes!

Thanks Mick I’ve thought about it but worry about trashing the motor and warranty, so maybe in a year or so’s time! How did you do yours and how do you find it, has it impacted on how far you can go on a full battery charge?

Curious about this too how do you do the controller mod and is it actually safe?

can you detect how many amps it delivers after changing the controller? the mx 03 has a very good battery, a good 1000w motor (I don't know if peak or continuous), but an underpowered controller that gives the motor about 450 watts of power. (9 amps continuous at 48 volts: 9x 48 = 432watts). I am thinking of replacing the controller with a 30a kt controller, which delivers 15a continuous and 30a peak so as to have more torque and a continuous use of about 750watt. but if you want there is also one from 40a peak and 20 to continuous, but with this I am afraid of burning everything. can you tell me how many amps your bike is delivering in these 500km you've done? thank you

The European and UK warehouse is in Poland!

Don't really know as I mainly use PAS 1 and 2 to get the maximum out of the battery and only use the throttle occasionally. The mileage you get depends on how much pedal assistance you use, the terrain and how hilly it is. We don't have much flat terrain here so it's either uphill or downhill!

Depends where and how you use it. I use mine off road and the odd cycle track and rarely go above 15 mph. Having said that because of the 30 Kg (approx) weight the throttle would be pretty essential for a steep hill start if you are not extremely fit or if you have injuries, disabilities or are just decrepit like me!

Hi Ron just a quick note about a very important subject I've been watching a fair few videos of e bike battery catching fire and exploding with devastating consequences do you have any concerns about the battery were using on the mx03 have you done any research into this yourself it seems to be on the rise id like to hear your thoughts on this subject kind regards thomas

@@thomasryan4124 I've not seen these videos on exploding e-bike batteries though plenty on exploding smart phones, tablets and cars! In any case you need to be careful with all Li batteries and not overcharge or puncture and stick to genuine parts!! Do you have a link?

All the videos are on RU-vid if you type in the search bar e bike batterys exploding a building in nyc when on fire from a battery exploding

Front one has been fine but rear used to rattle over rough ground and can hit the wheel which can bend the steel bracket if you hit any big bumps causing the wheel to rub against the plastic mudguard. I took mine off when I got a rack as that provides plenty of protection. You could easily attach the mudguard onto the rear rack if you have one.

@@RonWalkerCairngormGuides Thanks Ron...

Hopefully it lives up to your expectations! Let me know how you get on?

It's uphill all the way until the tarmac road!

Should be info on RU-vid and the manual but will get back to you if you can't find it!

17 inch frame with 26 inch fat tyres

Hi, I am 5’ 8” would this size suit me, please? Not rode a bike for some 30+ years but looking to get one for retirement and eBike appears to be perfect, if I get knackered peddling. Great video Ron! 👍

@@rayerdinc2441 I'm 5'8 too, so should be OK!

@@RonWalkerCairngormGuides Thank you.
