Thanks man! This clears things up. I don't have a surron but a enduro ebike with a homemade 72v 36ah battery (~2500wh). Did my first range test on the street the other day on urban/suburban roads at speeds between 0-50mph, ~1400ft elevation gain, lots of braking, and made it around 35 miles. Thought something was wrong!
I have noticed a huge increase in range of about 30 to 35 % when I upgraded from the stock 48t steel rear sprocket and stock O-ring chain to an aluminum 58t rear sprocket and a ProTaper chain without O-rings. I weigh 160 lbs. and ride with about 20 lbs. of riding equipment.
Thanks for your feedback man. Yes o-ring isn't the most effective type of chain, it has other advantages, but like you, I'm better with standard chains. I made a test with different sprocket sizes and didn't notice a significant difference though. I think it depends on the terrain. See the test video here: ruclips.net/video/_NurZ97J2EQ/видео.html
Sure I did. I'm 170cm, so yes I can get on a petrol bike and have ridden them quite a lot. For my size though, the Surron is perfect and overall, I love the fact that it's lightweight. I come from mountain biking and I feel at ease on the Surron!
My personal experience with my SRX is that I have never gotten more than 24 miles and the battery would cut out at 19%. I rode at full power always and weigh 230lbs.. With my bms bypassed stock battery and ASI 4000 pushing 7500 watts with 20% regen and 5% field weakening, I now only get 18 miles max. Cheers.
That's interesting! Obviously it depends on the elevation gain and average speed. Your battery indicator definitely has an issue, it shouldn't cut-off before it gets under 10% (at least its the BMS bypass it's not relevant anymore). Is this on road or off-road? In any case, weighting 230lbs (104kg) these are pretty good numbers!
@@MTO_Brothers these are 75% on road and 25% off-road numbers...the stock battery panasonic cells are very weak....nothing less than 21700 molicel cells are fitting...
@@budwhite9781 talk about a buzzkill sen many people get way more range than u you must ride hard and whiskey throttle everywhere plus ubwill get that range cause anyone over 200 pounds this bike really isnt made for them its a small bike for smaller lighter riders
Yeah 18 miles is pathetic imo. Untill you can rip it like a dirtbike all day long and you still have battery left to drive home, only then i will consider buying one.
salut merci pour cette vidéo. Je m’interrogeais pour le remplacement d'une de mes motos par un Surron malheureusement l'autonomie reste faible et je cherche une certaine polyvalence. bien que des sorties de 2h00 à 4h00 pour de l'enduro sont plus fréquentes. je fais aussi des boucles de off road avec des liaisons routières de 400km sur 2/3 jours. ce qui reviens à garder plusieurs véhicules. le rapports poids puissance du SURRON est intéressant pour du off road très technique. je vais patienté il y a le prix qui fâche pour un 50 cm³
400km la y’a vraiment qu’en thermique ce c’est possible ! 2 a 4h en revanche avec une bonne batterie c’est tout à fait jouable. Je dirais que chaque engin a son usage.
Je reviens d'un ride et je vous donne quelques données. C'est un full stock (batterie 60V, couronne 48 dents) et je pèse 60 kgs. Je suis parti avec 86% et je suis revenu à 27, soit 59%. Temps de course : 1h12, Distance : 31.53 km, Vitesse moyenne : 26.40km/h, Vmax : 63.38km/h, Montée : 664 mètres, descente pareil avec frein moteur au max (mode E3) et récupération d'énergie.
@@MTO_Brothers Je viens de commander une batterie 60V52Ah et on pourra comparer l'autonomie face au setup de base. C'est mon premier upgrade, on verra bien 🤟
Well explained 👌 I can give you a very good example, i weigh 90kg and use 70Wh per km offroad. You only use 40-50 Wh/km at about the same power. Thats 40% less 😅
And that makes sense, you're about 40% heavier. Then the variance will be about terrain, elevation gain and riding style. At some point, we can't beat physics 👨🔬
salut ! j'ai regardé la plupart de tes videos et elles sont vraiment supers, comme ton anglais ahah ! Serait il possible de nous faire une vidéo dédiée aux améliorations du contrôleur et de la batterie ? Les modifications nécessaires, le prix moyens des modifications et surtout où tu as trouvé tout ça ? Je voudrais booster un peu une light bee X car en cote avec mes 85kg c'est faiblard :( Merci pour tout ton contenu :)
Salut ! Merci pour ton commentaire plein d'enthousiasme, ça motive pour continuer 😀 Oui c'est prévu de faire une vidéo upgrades, il nous manquait encore 2/3 choses afin d'avoir les moto au propre. Sans chercher trop loin, si tu veux plus de couple, tu peux changer ta couronne, tu perds en allonge mais tu grimperas aux arbres ! On vient de poster une vidéo sur le sujet ;)
not into this sport at all, but actually there's some pretty simple rule of thumb math to get a pretty good estimate in comparison to a regular petrol powered bike IMO: A good petrol-powered engine is generally about 1/4 as efficient (tank-to-wheel) as an electric motor. For 2 stroke engines it's even less, probably much less actually, so let's say 1/5 as efficient. 1L of regular petrol fuel contains 8,4kWh of power, so a petrol powered bike with 1L of petrol fuel in the tank would be roughly equivalent to an electric bike with 1/5*8,4kWh=1,68kWh -> 1,68kWh battery. (of course there are still other factors like weather conditions, both are going to perform worse in cold weather, the battery powered bike more so though)

That's why it's always so difficult to answer people when they ask about range…

The Surron has never before looked like a full grown bike. I guess this is really fitting to you. Did you ever manage to get on a petrol enduro?
Sure I did. I'm 170cm, so yes I can get on a petrol bike and have ridden them quite a lot.
For my size though, the Surron is perfect and overall, I love the fact that it's lightweight.
I come from mountain biking and I feel at ease on the Surron!
can you do a road ride video?

How is it with the 72v battery can you ride longer now?
The 72V is more powerful but doesn't necessarily pack more power. So I ride it a bit longer (and with more power), but not by much.

You’re ignoring weight in your equation, yet that matters a lot!
Interesting, as always
Thanks bro!
Thank you
j'adorerais une vidéo "faq'' j'ai des centaines de questions :p
55kg dam you must fly on that thing
Trust me I do! now with the 13kW, I rarely need full throttle 🤣
how the hell u only 121 pounds my 5foot2 gf almost weighs as much as are u like 12 or something ?
I guess my bones are quite light 🤷♂️ I’m not fat either though
I’m 5foot7 so a bit taller than your GF.
@@MTO_Brothers lucky for ebiking more range for you haha

je suis preneur aussi !
