Only 200m long but 20% according to the signs
No problem🙂
 
Has anyone had trouble with retaining screws coming loose on the rear hub wheel ? I noticed a load creaking sound the other day that transfered up the rear of the bike into the seat . When I got home I did a quick visual check beliveing that I had another spoke pop on me . It wasnt to be as I noticed the retaining screws coming adrift . I attempted to tighten up with no luck as it appears that what ever the issues is has stripped the thread within the housing and screws just go round the other 3 screws just required tightening up there appears to be an issue here . I have sent a vid and pictures to NCM and await a reply . the bike is still under warrenty
 
Received the new wheel with motor. No tire attached. I can’t install this myself and will need to bring it in to a service shop.

Hi mate why new wheel ? I have had an issue with x3 screws that have come loose and damaged the housing threads I have emailed NCM with a vid and teh screws . they carnt be re tapped I believe new wheel is in order
 
Thanks for the response. The hill I was on is a pretty steady 10-14 MPH hill, but there are a few slow sections where I may have dipped to 8 or so. I also noticed that when it occurs if I quickly stop and lift the rear wheel and hit the throttle the noise and vibration are still there with the wheel freewheeling under no load. After a few seconds idle it snaps back to normal operation. The Leon Cycle folks think it may be a controller. Their Moscow Plus ad states "...there's no mountain you cannot climb." Hopefully that also applies to this 8% grade paved road.
Sadly, a new controller had no affect on the noise and loss of power after the very repeatable 8% grade, 5.5 mile climb at PAS 6. I think I agree that this may just be a limitation of this bike. This bike will climb crazy steep hills as long as you're wailing on the pedals in low gear, but long power eating climbs are not its strength. I believe the internal motor and electronics temperatures get too high and there isn't a graceful limiting mechanism, which results in motor drive noises, loss of power, and eventual thermal shutdown. Now I pull over and let it cool a few minutes when it starts to grumble, then continue on my way. Hats off to Leon Cycles for a quick response and trying all reasonable cures, but every eBike has its limits.
 
I´ve put 2700 miles on my moscow & i love it, but I have encountered some interesting mechanical dilemnas. Right off the bat, if youŕe
looking to buy one, get the moscow +. It worth´s it. You´ll need to be a fair to middlin´ bike mechanic & will be frequently adjusting the mechanical
brakes. The plus has hydraulics, & they´re worth the extra price without the other upgrades that come with it. In truth, this is not the best bike for a
novice. On the other hand it´s cheaper than making newbee mistakes on a $5,000 bike. I´ll repeat, memorizing the manual will spare you
the other half of the learning experience. A basic knowledge of generic mtn. bikes would be ´very´ useful.

Update, the regular moscow is now $1059. That´s probably as much bike as you´ll find at that price.....
,but that said, there are somethings you should know. Before purchase, plan ahead. At 2000 mi. you
should probably replace brake pads* & chain. Ordering ahead of time will save a lotta down time.
Mechanical experience will be useful. Again, the plus is the best choice if you can afford it. Stock tires
are fine, but if you are a heavier rider, I´d suggest getting something with tougher sidewalls that can
handle greater pressure at least for the rear, 55 to 70 psi.
*20mm x 30mm pads
 
I'd suggest calling them. They are slow replying to emails.
I haven't even got my bike yet, it's in limbo between processing and delivery. Amazon shows it as shipped but so far no tracking no. I've contacted Ryan Ritchie (Seattle) on several occasions an get a response within 12-48 hrs.
 
That would be 48/16 or a 3 to 1 ratio. I´guessing you are a lighter rider than I am at 225 pds. If that´s comfortable, go with it.
The modes on a moscow are more about the speed you want to travel than power. lower gears give you more leverage
against the pedal & reduce effort. It´s basically about finding the sweet spot that works best for you . On the flat, (theoretically),
mode 1 in a low gear at low speed,( 10 to 12 mph.) will provide max range...., but the world is not flat, people have different
levels of fitness & weight, & want to travel at different spds. As it sez in the manual,( I concur), try using all gears & modes to
familiarize yourself with the bike´s capabilities. Remember to ease of the pedals for a second as you shift. That saves wear & tear
& makes for smoother shifts. Find that sweet spot. Be safe & situationally aware!

Just realized you are in Italy, so I guess your dealing with the EU 25 Kph limits., That´s simple enough to change to mph, but don´t get
caught🤪 (Itś in the manual). Hope you don´t ride like Italians drive. (just kiddin´)
What? The world isn't flat? Don't tell QAnon!
 
I have found my problem, inadequate wiring from battery mount. I have asked Leon to send me a new one but I don’t think this particular part is up to the job So I may try to upgrade the wires somehow.

with regards to your issue , I can only assume either a loose spoke or 2, or some problem with the motor . Both would be apparent under load so good luck. I have just replaced my controller, display, sensor etc which took me about 2 hours and then I found my wiring problem so I didn’t need to do any of it 🤪🤪🤪🤪🤪
If that's all it was, do you still have the original parts that were replaced? If so- bonus!, I'd rather be trouble free, but if you now have spares, good on ya!
 
Eureka, Have retrieved lost images! this is so handy; I can rock either wheel off the ground to check & adjust brakes,
remove & repair tires, & more easily mount a trailer, & I have the rear mounted kick for unlevel surfaces.
The modified rack has a 2nd platform below the top to carry a second battery allowing for more range than I´d
care to ride in one day anyway. Mounted high, it puts the panniers behind my thighs to reduce drag & heel strike,

December 25, 2014? I'm assuming you just haven't set the date on your camera, or is your bike really 6 yrs old?
 
One issue I´ve had is the tire slipping on the rim. In two instances the tube folded back on itself & burst at the valve; in a 3rd it
actually ripped the valve off the tube. Only once was it actually punctured by a broken wire in the tire bead. As heavy as I am,
this bike produces instant torque on take off & the rim moves before the tire does. Likewise with full throttle uphill or hard
braking down hill. The wheel has a slippery plastic rim strip that should be replaced with a rubber one, even if the manual threatens
to void warranty. It is extremely important to keep just the right tire pressure. Too much will pop the tube,(especially in hot
weather). Too little & the tire wants to slip on the rim or bottom out in holes or bumps. I think ´lightly´ sanding the inside of the
rim where it clinches the tire bead.help prevent slippage. Flats are a major bummer, but on the up side, I´ve become quite proficient
at fixing rear hub motor flats.🤪 You really should learn to do these things yourself unless you are made of money. 15 euros is outrageous!
I'm seeing alot of the experienced serious eMTB riders swearing by tubeless, seems to me it would be more prone to blowouts (although no more pinch flats). I don't quite see the advantage other than saving a little wheel weight... I suppose if you have sponsors, they do all the grunt work, and cost is not an issue with their $10,000 bikes.
 
Rear rim is bent on my moscow plus. No idea how. Only have 80km ridden. It's definitely not from using throttle from a stop....I have never done that....I had it trued as straight as possible, but the rim needs replacing.

Leon has not gotten back to me after multiple attempts the past week. Just purchased the bike 4 months ago.
Any ideas of wear I can get the parts to build a stronger rear rim??

Leon hasn't replied at all? That's surprising, for me I had an issue with damage from shipping and they got back to me in ~6hrs. I went through email ([email protected]) and filled in the web "contact us" form.

After 3300 mi. I had a rim issue a few days ago; hit a pothole that ripped the spoke nipple right out of
the rim, horrifying. I initially though my wheel was a right-off. Luckily, I had some small grommets I
use in leather work. Mashing 2 male grommets together with J.B. Weld, I glued & pressed them into
the hole. They were a perfect size to receive a spoke nipple. After seating the nipple, I inserted a spoke
& tightened it up. Since the glue set, the wheel has been good as new.(what luck) I definitely think
NCM should be using grommets for their rims as I have seen in the rims of other ebikes. As for your
problem, George, I´ve can only guess why your wheel tacoed. Even after my rim issue, the wheel is
true within a mm. It could be that since spokes are probably tightened with a power screwdriver, they
may have been too tight, or perhaps there was a metallurgic imperfection in the rim. Labelled a Mtn.
bike, the moscow is designed more for getting up a mountain than shredding down one. Yes, I think
the rims could be improved, but the problems I´ve had with rim & spokes have been my fault. I find
it hard to imagine what it would take,(heavy as I am), to taco one of these rims.
