Hi all,

I've been lurking slightly in research and seeing as this site has been so handy I thought I'd contribute! I bought a Gocycle coming up to a year ago, and on Saturday received delivery of the Pro Connect S, so I'll do a cross-review of them - there are plenty of photos around so I couldn't be bothered with those though :p

Gocycle

Originally bought an ex-display model from a local Evans who had it in the window. Unfortunately however, I hadn't cycled or been on the road in any responsible sense since early teenage years, as in the years between I didn't trust myself to 'drive' AND enjoy cannabis, an essential spice of puberty :rolleyes:

Anyway, I crashed it in to the side of a van on my first commute in (no, I hadn't been smoking..), and people don't believe me when I say it but it was absolutely my fault. Learnt caution, and now feel hopefully that most bike accidents are driver error :/

The Gocycle came off a lot better than I did - it wasn't that severe a collision as I had about two meters to brake, but I had started off at full speed and still fractured two fingers - i managed the rest of the commute in shock and luckily the bike still functioned as if nothing had happened and dragged me the last mile in to the office - however, as the rear wheel was slightly askew (and that probably wasn't a result of the crash as i went in face-first) the Evans people offered without any prompt from me to replace it with a new one when I took it in to be looked at. So at the mere cost of a few months without the use of one hand and an ugly scab on the helmet-line, I achieved a reduced price on a new Gocycle :p

After recovering and getting a good 6 months use out of the new Gocycle, I'm still very happy with it! Besides obviously standing up to quite a beating, the battery :: almost :: always lasts me the 13 mile commute home, but if I feel lazy or the weather is too bad, it very quickly folds up just the right size to fit in the doorway of a train.

Obviously the machine looks fantastic too, unlike anything else and the entirely enclosed chain is a real bonus for a) someone who hasn't tinkered with a bike for years and b) a commuter who doesn't want to get work clothes caught in a chain. I don't know what's in there, but it's done it's job fine without any interference from me.

I have a two really long, increasingly steep hills on the commute - I don't know what their gradients are but they're the kinds of hills most people will get off and walk for. With the Gocycle I can fly up at least equalling the speeds of the lycra-clad types - without standing up - which often causes them to chase you up to the top of the hill and outpace you on the ride down ^.^

I should add that the Gocycle has a 'US/Off-road' mode which increases the speed limiter from the standard 15.5mph to 18.5mph ;)

To sit between the pros and the cons:

I was apparently the only person this happened to, but the big red 'Go' button disappeared from my cycle. I don't even know when - probably knocked it taking it through the door of my house as i noticed it about to go to work one morning. The bike still functioned if you pressed the below-the-button-bit.

Gocycle were bemused and wanted to see the bike, so they sent me a box and gave it a free service. So it's a minus as it happened, but a plus as customer service was top-notch, despite my being a total wally failing to fit the bike in the box and requiring clearer instructions...

The cons:

Like I say, I'm really happy with the bike, but it does have a few limitations.. I'd say the Gocycle is pretty much a 'fair weather' bike - in the manual it says you're actually not supposed to use the bike when it's too wet, and there is some visible circuitry around a USB port on the front below the suspension :confused:
this is supposed to be so that when (if?) it's eventually released, you can buy software to modify the controller to go up to 35mph. And presumably it's placed where it is as that's right next to the hub motor. But you'd think they'd at least plug the damn hole! Rather worrying.

Having said that, I and many others have occasionally used the bike in the rain and it still works fine.

Although, if you fold the bike to prop it up in the closed doors of a train, make sure to take the mudguards off first if you have them (it's not hard - one knob to unscrew), as they will snap against the walls of the train, and you'll soon have a muddy-bum.

The motor can be a bit noisy - it got probably twice as loud within a months use, and has maintained it's decibel output stably since. I don't really mind, it's obviously an electric bike and at least people can hear you coming if the traffic's not too loud. It can sound a little ugly occasionally though which makes me worry for the life of the motor. These are not for sale on the gocycle website either...

There are only three gears on the bike, and unless the battery runs out, I'm always in the third (even up the steepest hills). The motor really is pretty capable so generally you can stay in the top end of the allowable speed range. Downhill, higher gears would be appreciated. But then, it's an electric semi-folder, the Gocycle is designed to take the effort out of cycling - not make you the fastest one around.

The only other downsides I can think of are the relatively limited range, and the slippy tires that come with the bike. While optimised for speed, they are certainly not designed for wet weather. I opted for the cheaper treadier tires that gocycle sell.

I look forward to seeing what the Gocycle 1.5 in 2012 and the Gocycle 2 in 2013 look like! I suspect lithium batteries...

Kalkhoff Pro Connect S (2010)

Having received the bike on Saturday, I was eager to take it for a spin. Unlike the Gocycle I hadn't had the opportunity to take a test ride (hence my extensive research mostly here!)

This was a very different experience to riding the gocycle. Immediately I felt that I was putting a lot more work in to the bike than I was used to - but I think this is a mix of my wanting to go fast, and not being used to actually having to change gears. Certainly it would be possible to expend less energy were I less concerned with my pace. That said, the ride isn't a sweaty one :D

my first ride i did a bit over 28km (that's what the bike measures in, as you're probably already aware..) with a top speed of 52kmph downhill (any faster than that and I'd worry for my life - it's definitely capable though if you cycle hard downhill) and an average speed of just under 30kmph

As the Gocycle doesn't have a speedo, I can only guess at an average of around 15mph/25kmph on off-road-mode.

I'm aware I'm generally travelling quite a bit faster on the PC S, but somehow, travel feels slower.. On the gocycle, I'll feel like I'm flying at 15-18mph but similar speeds on the kalkhoff just 'feel' slow. Can't really explain that. Perhaps it's all relative to top speed. The trip still flew by!

The next day I attached a trailer to the PC S to do some shopping. It's almost like the trailer isn't there when it's attached - it barely effects your speed. Admittedly it wasn't too full, but I was very impressed. I was keeping a check on my speed merely out of concern whether the trailer could stay attached at the speeds the bike was letting me reach.

Today came the first commute. I bought the PC S instead of renewing my annual travelcard - the costs came out almost exactly the same, so factoring in occasional non-peak rail use it should pay for itself in a year and a bit.

As a result of this factor I decided I couldn't pay for a travelcard today, despite the heavy rain and winds (not very used to bad-weather-cycling!). On with the plastic trousers etc., and though my speed was reduced, I pulled through without a problem. Definitely not something I could have done on the Gocycle!

on the way home, luckily the rain held back. The lights that come mounted to the bike, powered by the battery are really pretty good! My only minor complaint (but I also kinda like it) is that the front light is pretty broad so I might consider adding your more standard torch-like front light for a more focused spot of light but it's probably not necessary.

with regards to hills, I'm sure I'm going faster now.. due to the weather there weren't so many other bikers around but the one other person I saw/overtook on a hill I seemed to overtake much more quickly than usual. Speed up the earlier, still steep climbs was about 25-30kmph slowing to just over 20kmph at the steeper tops where most people would get off and walk.

On long, constantly steep hills it can be a bit of a struggle, but probably only because I don't want to let the speed get below 20kmph, you could probably idle up the hill in one of the lower gears but I'm not really the right person to assess which bike could get you up the hill with least effort. I suspect the PC S would be a little easier going in the lower gears than the gocycle because it has more power.

Also, this bike is totally silent until you change gear. When I overtook that guy, I could hear HIS bike whirring away but not mine - and his wasn't electric! hopefully this will continue to be true - could always get noisier with time, but that would be 'noisier than totally silent' so I guess I can't complain!

The braking is very good, better than the gocycle but I guess it has to be with the higher possible speeds! Both bikes feel very well made but the Kalkhoff has the edge. One thing though is that the Kalkhoff is much heavier. It's not a problem to quickly hoist the Gocycle under one arm and jump up the stairs but I wouldn't want to carry the PC S regularly. But it's not really fair to compare them, they're very different machines.

At first I quite liked the light, small metal pedals but I quickly realised they were tearing up the soles of my boots so I swapped them out for a set with some rubber on them.

Bought from 50cycles obviously, they were very helpful answering my questions and even arranged the Saturday delivery for me! Thanks guys! Only thing is the box was missing the alan keys/wrench and the mirror - luckily I had tools around, and probably would have removed the mirror which was on the wrong side anyway, but I could see the lack of tools being a problem for some so you are informed ^.^

The only major concern (having done a second commute, and forgotten to bring the charger with me) is surprisingly the battery. it's 13 miles in and 13 miles out so I would forgive the battery for running on empty on the second leg of the journey home, but after the journey in I was at 3/5 bars battery, about a quarter of the way in at the bottom of a hill i noticed i was at 2/5 but 5/10 minutes later at the top I looked down and I was reading empty. I could just about accept the loss of battery life (despite expecting a good 20-25 miles even on high power mode) but the rapid drop from 2/3 to 0 bars power is worrying. I guess I'll just have to keep track of my miles!

Despite reading 0 bars, the lights were still as powerful as ever, and when I plugged the battery in a moment ago two of the LEDS lit up so I'm not sure whether I've got a funky batter? :confused:

I had noticed the hill was a lot harder to climb than the day before, but I actually just assumed I was just tired from four long cycles over four long days till I read the meter. Which actually probably says a lot for the ease with which you can ride the PC S.

Conclusion

It really is hard to compare the two machines as they're so different, but hopefully this will be useful if you're considering upgrading from a hub-motor to something chain-driven - on almost every front the Kalkhoff Pro Connect S bests the Gocycle, but then it's more expensive, not a folder, and technically illegal to ride on the road.

Owning both, I will still use the Gocycle if I need to get on a train now and then or so a friend can ride alongside but the PC S allows me to commute come rain or shine or cancelled trains, and at a quicker pace.

If you're in relatively good health, I'd have no doubts recommending the PC S over the Gocycle as a dependable commuter bike. Otherwise, or for casual use, I'd definitely recommend a test ride. I think the PC S can be an easier ride in all conditions, but it requires more attention to gearing, and lack thereof could cause you a hard time if you don't have the strength.

If you're still reading, well done! Hope that was of some use/interest. And thanks for all those who written other reviews! They were very helpful.

As someone who hasn't had to deal with the mechanics of cycling I would appreciate any tips at all (no matter how simple) e.g. ideal tire pressure, necessary regular maintenance etc.

I have an S and have very similar experience of some days it feeling harder and not knowing why, certainly headwinds are felt the next day. Sometimes having the weekend break makes it easier, but others less so. I perceive a difference with rougher and smoother road surfaces on parts of my journey too.

Certainly having never checked them, when I increased the pressure of the tyres made it much easier to pedal, although of course tougher on the botty too ;)

Mine increased from about 30 psi to 70 (the range on the originals is listed as 58-85 I believe?)
