DOWNHILL44 Posted November 2, 2003 Report Posted November 2, 2003 So come on people can some one tell me whats this Power Spring rear suspension like anybody got it? is it worth it ?? is it better than Peter Lynn race suspension? p.s. i have a Libra Special with a 145 cm axle and am looking in too some upgrades for the near future. many thanks David Quote
rayens Posted November 2, 2003 Report Posted November 2, 2003 Talk to Stonemonkey - he has it on one of his buggies Quote
nigel Posted November 3, 2003 Report Posted November 3, 2003 Not to impressed with it. Got one a while ago. Springs too firm (650 pounds each!!) Some bits needed redrilling to make them fit. Changed springs to a lower poundage(at more $$$), it now works but has made me start to design and make my own. I think it needs more engineering work done on it before it is any good. 2/10 for out of the box 6/10 with the new springs Value for money??? Lots of money but not lots of suspension. Came with out instructions too. Quote
8015 Posted November 4, 2003 Report Posted November 4, 2003 All the rest of M2s parts look excellent - but I can't understand the reasoning behind the powerspring rear suspension configuration. There are 2 springs, yet the way it is arranged the whole axle will still move as one - so if one side hits a lump or dip the axle will still contour although some of the bump will be taken out. The PL race (and V-flex2) style acts on each wheel independantly so if only one wheel hits a lump or dip only that shock moves leaving the axle more steady, which obviously has more chance of keeping all 3 wheels in contact with ground. Clearly m2 do know what they are about as the V-flex looks great, but I can't help wonder of the powerspring rear suspension is more aimed at people wanting a softer ride than at those wanting to maintain grip over rough terrain? I'm sure I'll find out here! JIM Quote
Marcus Edwards Posted November 4, 2003 Report Posted November 4, 2003 Finding springs has been a right royal pain. The first PowerSpring used the same shocks as the PL which should have a 550lb spring with 450 and 650 available as spare parts. Well guess what no one can get them any more. (rumour has it that is why the PL monster was shelved) So we swiched supplier but could only get 650 which is ok for most pie eating buggy pilots but we are desperetly looking for softer springs. Here is the size of the spring we want. Anyone got some? 95m Long 30m Bore 7m Wire 450LBS/in Boater The PowerSpring is designed as an upgrade to the buggy to add suspension but keeping chassis roll to a minimum. The PL version when under side load from a kite alows the buggy to roll/twist. The V-Flex buggys are designed from scratch and have double wishbone independant suspension. Quote
lardyb Posted November 4, 2003 Report Posted November 4, 2003 bloody 'ell 95 meters long for a spring. and I thought my buggy was quite big. Is this a bit like that bt advert with "tiny tina "being ironic???? If you mean mm then I might know someone who could help. I'll let you know after I've spoken to him. Quote
Marcus Edwards Posted November 4, 2003 Report Posted November 4, 2003 I said they were for the pie eating buggy pilot but yes that is ridiculous. it should be mm Quote
nigel Posted November 4, 2003 Report Posted November 4, 2003 And if you are not a fat bloater, then the power spring is no good!! Springs can be made at spring companies!!! They will do any size and lbs to your hearts content. If the springs are no more, then you should have redesigned the system to accept more common size springs and shocks. That way you would not have these problems????? Like I said before, needs more engineering. Quote
Agger Posted November 4, 2003 Report Posted November 4, 2003 Originally posted by c_quad_squad Like I said before, needs more engineering. Why did you buy it then ???? To be first with a new toy ????? After all if I was spending my hard earned cash I would of made sure it suited my needs, then I would only have had myself to blame and not tried to blame someone else for my inadaquacy. :eek: Quote
nigel Posted November 4, 2003 Report Posted November 4, 2003 There are no people with one here in Australia!!! Nor any store to go and have a look at one. I got the power spring as I had a very long and rough trip in front of me ( Birdsville track, 520km of outback dirt road). The design of the power spring looks good, and the few reviews of it also say it is alright. So I got one. As for my "inadaquacies" If I can stop one person from buying this poor product then I think that I have acheived something. I have also contacted Marcus and told him that if I can not get it to work then it shall be going back to where it came from. But the responce has been almost nought. So Agger, you have never ordered anything off the internet without seeing it before???? Quote
Agger Posted November 4, 2003 Report Posted November 4, 2003 Originally posted by c_quad_squad So Agger, you have never ordered anything off the internet without seeing it before???? I always do my homework and have viewed a similar producy locally if I can't view it then I don't buy it. Quote
lardyb Posted November 4, 2003 Report Posted November 4, 2003 you really are a misserable tw4t aren't you???? 4 posts with either dump ass comments or just plain bitching. Does anyone else supply a similar product???? not that I've seen. we should be praising M2 for at least trying to use a bit of inovation and making new products availible to the public. Of course things arn't going to be 100% first time but what is??? Look at the first buggies availible to the ones out now. I think it's called PROGRESS Quote
Agger Posted November 4, 2003 Report Posted November 4, 2003 I have to agree with lardyB, look at Flexi with the Blade 3, you'd think after three attempts they'd get it right. It's called innovation Quote
8015 Posted November 4, 2003 Report Posted November 4, 2003 Originally posted by darkwater The PL version when under side load from a kite alows the buggy to roll/twist. Makes sense, I hadn't considered that aspect! Trying to work out if the rubber torsion suspension (like most trailers) that I've seen on a race buggy would be any better in that respect, I think it might be a bit because the wheels don't tilt just up and down. I take it the double wishbone system in the v-flex gives independant suspension and reduces chassis roll? And for about the same price as a non-suspension truck or cameleon or similar! If I wasn't so set on building a non-suspension buggy of my own I think I'd be seriously considering a v-flex! You don't list the wheels separately - do you sell them (I'll send e-mail too!)???? JIM Quote
Marcus Edwards Posted November 4, 2003 Report Posted November 4, 2003 I think c_quad_squad we have had quite a bit of corespondence re your PowerSpring and the last email I sent I said when I get hold of some softer springs I will send you some to try out. However I still can't find anyone who stocks our size or will make some for a resonable cost e.g. the last quote I had was £50 each spring unpainted. I am sorry you don't think it works for you, is it ok now you have put softer springs on? what lb are they where did you source them from? can you give me there email address please. Quote
HD462 Posted November 4, 2003 Report Posted November 4, 2003 I don't know the sizes or weights off hand, but have you thought about the suspension units used on mountainbikes? Would they be suitable? Just a thought. Quote
Marcus Edwards Posted November 4, 2003 Report Posted November 4, 2003 Err, yes. That is what we use, but try buying just the spring that goes on the shock. In fact next time you are in a bike shop ask them how much a replacemant shocker is for a mountain bike. I have been let down buy soooo many suppliers on this one it is getting beyond a joke. In an ideal world I would use the ones that use just oil and air pressure and are totally sealed but they cost upwards of £200 each. If I buy 1,000 of them from China I can get the price down to $4 each but even then I was not happy the guy knew his newton force from his lb ow. Quote
HD462 Posted November 4, 2003 Report Posted November 4, 2003 Depends on what quality shocker you want I guess. You can buy a complete suspension bike for £80 now, but how good the shocks are is another question. If they're selling a full bike for £80, the shocks they use can't be that expensive. You could buy complete shocks, and just use the spring I guess, if they're cheap enough. Just put it in the price. But if you want to use quality Rockshox type shockers, then they're gonna cost money anyway I guess. Although an example at Wiggle are showing replacement springs for Marzocchi shocks for £9.99 but no rating shown. See here Quote
8015 Posted November 4, 2003 Report Posted November 4, 2003 The shock on an £80 bike will have virtually no damping, you'll be lucky if it has a real spring and not a chunk of rubber! Anyway, if these guys can't supply springs (I've checked, they can't at the moment) things are looking pretty dire. I'm checking back from time to time to see if the adjuster knob I need for my front fork comes into stock, (I don't have much hope - the UK distributer was extremely vague but I'm hoping a batch appears in the US sooner!) so I'll try and remember to check if they get any rear shock springs in. They aren't likely to be cheap as bike spares - the plastic knob I require sells for £25 or more over here (will be cheaper from the US!). It looks to me like m2 are doing what they can to support the units they have already sold - whereas their suppliers can't be ar$ed. Anyone with a PL suspension unit should be equally concerned if the supply has dried up! JIM Quote
DOWNHILL44 Posted November 4, 2003 Author Report Posted November 4, 2003 Well i think i have opened a can of worms here i just want to upgrade my Libra i am 19 stone so the power spring might work well but on the other hand there's a lot things to think about also its £170 which is'nt cheap but as some one said it looks great and its one of the only non Libra parts avalible to upgrade many thanks too you all giving me your views i think i will just have to wait till i see one down pendine one weekend (someone's bound to turn up with one one day)looks like itsback to soft tyres for a while. Thanks All David Quote
lardyb Posted November 5, 2003 Report Posted November 5, 2003 theres a bloke called rico from cardiff who is fairly regular at pendine who has the m2 kit on his libre. he drives a big old blue volvo and his son mountain boards at the same time as he buggies. Keep an eye out for him to have a go in it. If he says no come and find us and we'll nick it off him for you to have a go Quote
ashsmith Posted November 5, 2003 Report Posted November 5, 2003 Why not contact MoJo in Newport, Wales. They can rebuild shocks to any spec. Why do you need twin shocks on a single swing rear end anyway? Quote
Marcus Edwards Posted November 5, 2003 Report Posted November 5, 2003 Originally posted by ashsmith Why not contact MoJo in Newport, Wales. They can rebuild shocks to any spec. Why do you need twin shocks on a single swing rear end anyway? Do you have a contact number for Mr MoJo? Do they sell spare springs? How much? Twin shocks were a simple solution, a single shock would of created more problems than it is worth as you would need to stop the structure twisting and construct pivots in the middle for a single shock.

ashsmith Posted November 5, 2003 Report Posted November 5, 2003 Try http://www.mojo.co.uk. Mainly fox springs. They have a spring calculate on the site that gives you a price. Quote
ashsmith Posted November 5, 2003 Report Posted November 5, 2003 How about making a set of your powerspring forks with the footpegs suspended? Quote
