    Hi guys, I just found this announcement by the Russian company Ecodrift, great news for the Inmotion V8 fans ! It should be called V10 or V8 fast. The specs will be : - 16 inch diameter 2.5 wide tire - Exterior aspect similar to the V8 with the V5F trolley handle (no more integrated trolley ??) - Available in 640Wh & 920Wh (good news) - Max speed of 40kph/25mph - Wide and high pedals - Weight of 18kg - Coming in Mars-April of this year See here for original description : http://electrotransport.ru/ussr/index.php?topic=52495.0 What do you guys think about this one ??? Can't wait to see the first pics
  2. The Photo Thread

    Hi guys, the weather was sunny (but cold), I grabed the Dualtron Ultra for a 30km city ride

    Hi guys, here is a short video for the promotion of our next scheduled group ride in the east of France
  4. @meepmeepmayer This 1.6Kwh ACM is still working good today in the hands of someone else (sold), it's around 16 000km today. I hope it'll last another 15 000km I would be very curious to see a +100 000km EUC, however I think only the +1.6Kwh EUC can do it, because considering 1000 charge cycles, a 1.6Kwh EUC would last about 100 000km. The +20 000km MS3 of @Hansolo had the motor bearings changed. @Jason McNeil Could you put a prize on the first rider to each 30 000km ? That's more reasonable even though I think not that easy to achieve I think the top mileage out there is somewhere between 20 000km & 25 000km
  5. KS 18S Heavy back and forth oscillation

    Hi, I have experienced this a few times on the Gotway Monster unfortunately.... I also had another failure last week, the Monster is now unusable I can't say for sure what it is, but I can say the cold is not the issue, I think it's a bug in the firmware of the motherboard. Ask @Marty Backe he has a KS18S I think he never experienced such an issue but maybe he knows about someone who did ?

  7. Hi guys, I'm just back from a little ride with the Gotway Monster, everything was fine, I was cruising at around 30kph, I slowed down when going through the green pedestrian light on the bike lane, but at the moment the Monster rolled on a little bumb, it started to wobble severly back & forth, I fell on my my knee, right hand & shoulder, I still feel the pain a little. Fortunately I was not too badly injured, I just killed my phone protection and cracked the shell of the Monster. I still can't understand why it behaved like that ? @Marty Backe you experienced the same issue with your MS3 didn't you ?
  8. The Monster tried to kill me !

    Hi Marty thank you for your answer, the bump was really little, I'll try to take a picture of it this afternoon. I really don't think it's a normal behavior because I've passed on this bump a few times with the ACM, Monster, V8 and they never failed befored, could be the yesterdays temperature (-5°C). It seemed to be an oscillation to me but with very wide aplitude. Not sure if this can happen to any EUC board I hope not. The production date of the Monster is December 2016 but the motherboard was changed in July 2017. I was not a serious bump, I'll try to take a picture to show you guys, I always slow down before major bumps & cracks. This is certainly not a normal behavior, I had a Tesla & it never had this symptom even if I was hard on it.
  9. Hi guys, So I have been thinking about this for a while, what are the benefits of having an EUC over a bicycle in a city ? I have been riding a bicycle for about 15 years, it was my main mean of transportation, in my city there are numerous bike lanes so it's not a continuous danger by having to ride on the road. The EUC does almost everything a bicycle does, but it's more expensive, but here a few things I considered. First, an EUC is fun to ride, you get something you don't get when riding a bicycle, this is an obvious point. I had several E-bikes before getting an EUC, E-bikes are fun but they had a major flaw : they are attractive. I wasn't taking it out for anything else than a short meeting, or a trip where it will always be with me, and even by leaving it a few dozen of minutes, it got scratched by others...I also had a few "normal" bicycles that got stolen, one even got broken on purpose in the basement of my building. As for the cost of a normal bicycle, if I want something usable and practical I have to spend about 300-400$ on it, with the risk of it getting stoled, I would say I had 1 bicycle sotlen every 2 years, plus the maintenance that cost about 50-100$ per year. With an EUC, I bring it everywhere, in a store, at the cinema, while shopping..while the bicycles has to stay outside, even when at home, there is a risk of getting a bicycle stolen while it's not going to happen with your EUC, and if I decide to bring my bicycle in my appartment, then it's taking a lot of space, while the EUC takes a more reasonable space. The other major advantage I see for EUC, is that it has a better range than most bicycles, I mean not that many people ride 50km. E-bikes do have this kind of range too though. I think I also go out more often on my EUC just to ride, alone, with girflriend, with a friend...just for fun ! I have also done it on a regular bicycle but not that often, and I was always limited in range. I see three disadvantages with an EUC however, I think they cost more than a regular bicycle, and they don't like the rain, I know riding under heavy rain with a bicycle isn't fun, but there is no risk of a shortcut, and finally you don't do any physical exercice but that's not the point on a bicycle in general. What do you think ? Some of you guys decided to abandon your bicycle for an EUC ?
  10. Hi guys, I have to give you a warning about the Rockwheel GT16v2 (the last generation with the new tire and flat pedals). My friend just had a cut off today, without any warning the GT16 stoped working and he fell on the ground, he was riding on a flat surface at 44kph. Fortunately neither he or someone else was badly injured. We are investigating the cause of this, is it a malfunction ? Are all the GT16 concerned ? For the safety of all you GT16 riders, I recommend you keep it "slow" (under 30kph) until I get further info from Rockwheel about this issue. UPDATE : The GT16 has no "80% power beeping" like on gotway, you MUST keep it slow when the voltage goes down ! Here is some pics of the GT16 after the crash :

    Hi guys, here is the first video of our group tour in Metz (France) today ! More videos to come

    Hi guys, here are a few pics of our 24 rider group tour in Metz (France), 35km, lots of fun !
  13. [UPDATE] WARNING GT16v2 cut off

    Hi guys, So I got some update on the reason for this "failure", it is combination of high speed riding & medium battery percentage, and I have learned something VERY IMPORTANT : there is NO 80% power SAFETY ! So you GT16 riders MUST correctly set your alarms & tilt back, I highly suggest (if you are 75kg max) that you keep it under 40kph, and under 50% battery to keep it under 35kph, I am very sad that there is no progressive warning like on gotway, kingsong, inmotion.... Keep it safe !!!!
  14. how to enjoy riding slow speeds?

    Hi, I think riding slow is one of the best thing you can do on an EUC, just like high speed riding. I often find myself just cruising around at pedestrian speed (around 5 to 10kph), I don't think there is a need to do any fancy stuff (360, backward, freestyle...), just enjoying the glide, knowing that at any moment I can move along and go back to cruising speed, enjoying the scenery, the animals around (sometimes the people)... I'm probably one of the fanboys who think that EUC is just fun anytime anywhere at any speed. If my TG3 that tops at 12kph could have more range than 5km, I'd probably take it out more often, just enjoying the silence of the 350W motor. What in the world can beat a slow ride around a lake at sunset in summer with a slight breeze ?
  15. [UPDATE] WARNING GT16v2 cut off

    @KingSong69 Yes I know there is a table with the recommended speed, it's even 35kph, but Gotway recommends 25kph max, if there was a warning before the cut off I would say it's the riders fault, but the fact that there weren't any audible warning or tilt back is what concerns me (I wasn't with him when he crashed). @meepmeepmayer The official max speed is 55kph, and the GT16 has proven capable of approaching these speeds. The guy only sustained minor injuries. With gotway there is the continous beeping when reaching 80% power, with Rockwheel it's supposed to be alarm + tilt back.

    Hi guys, Tough riding under wet snow ^^
  18. Hi guys, When I first bought the Gotway Monster, it was because I loved the stability of this EUC, I thought it would be a very comfortable ride for long hot summer rides, and it delivered ! Even though I "only" have the 1.6kWh version, I still managed to get 120km at moderate speeds during this summer. However, since then, the cold & bad weather has come, I lost interest in it for months, because my "14" or "16" seemed more practical to me for an every day use. I commute to work every day between 19 and 36km, sometimes 54km, not including other stuff that I do with my EUCs. For the last week, I asked myself : can the Monster still have any practical usage ? Can I actually commute with it ? Knowing that I ride exclusively in the city during the week. So I forced myself to ride it every day, with sometimes 4 floors to go carrying the 26kg of the Monster ! I thought it would be very painful, I also tought that the size and manoevrability would be a disadvantage. I discovered that it is actually usable for commuting ! Yes it's not easy to carry around, but to ride along, it's great ! The stability gives me confidence, it absorbs road imperfections like a champ, not bothered like my "14" that I used to use every day. It's agility needs to be mastered, but I can do the same thing that my "14" can, it's just that it needs more "body" to do it. My conclusion is that while it was very strange to use suche a big EUC every day, it has a bunch of advantages that makes it very usable on a daily basis, plus I don't need to wonder about my range anymore (it would give me at least 60km at very high speeds even in a cold weather). I am also happy to tell you that it handles very rainy/wet weather with no issues at all ! Oh and for reminder, I weight 60kg, I am quite small, so it's not an "easy" EUC for me. I think I found a new usage for my Monster, I'll keep you guys updated, but I intend to use it every day until the Summer brake in late June !
  19. @Marty Backe It's hard to ride in heavy wind but still possible with this beast ! Oh BTW, here is a modified picture that suits better the tough guy on the picture !
  20. Hi Marty, Beautiful scenery & a cool looking guy ! I agree with you, the Monster is so stable that it's not bothered by the wind like other EUCs, I had my training 14 inch wheel TG3 the other day, just for a very short trip, the little breeze was enough so that I had to compensate by turning my shoulders to counter the wind's effect. On the other hand, the Monster, even with the +115kph winds we had here in France from the passing storms, weren't enough to put the Monster down, even though it was still a challenge to ride in these conditions. Skills may help you to ride any wheels in any conditions, but not with the same pleasure
  21. What's the biggest thing you've carried around on an EUC?

    Hi guys ! Here is a pic of the heaviest thing I've carried around

    Hi guys, here is a little group ride with 3 GT16, 1 dualtron ultra, 1 ACM & 1 KS14C Enjoy !
  23. The Photo Thread

    Hi meep, It's recognizable by the "KS sports" or "Kingsong sports" written on the the pads of the KS16S, and because the KS16B doesn't exist in grey, the KS16S is only available in grey or black, the KS16B is in white or black
  24. The Photo Thread

    @Vik's@Smoother It is a gotway MCM4 v2 HS or MCM4 Pro On the first picture, it looks like KS16B(with Msuper3 pads)/KS16S/Msuper3s+/MCM4 am I right @Michael Vu
  25. Rocwheel GT16 92V coming soon (2018)

    Who thinks this is a GT16 92V prototype ?
