This topic was "First impressions of the Raptobike low-racer", but I renamed it after my test commute, scroll down for video goodness...
Well, last night I had a test run on the Raptobike courtesy of David of Laid Back
in Edinburgh, and I promised to share my thoughts for what they are worth!
Just so everyone understands, my previous experience of recumbents has been half an hour fooling around in a park on a bunch of different models (all practical, more upright style 'bents) again courtesy of Laid Back as part of the Dutch cycling dreams exhibition. I had about an hour on the Rapto with David giving me tuition the whole time (for free - what a service!)
In retrospect I have rambled out a huge post so have shuffled it under headings, apologies if it seems a little disjointed.A *low* racer
First the obvious: it is extremely
low and makes no apologies for this! The seat is ~25cm off the ground and can be reclined at just 20°. Yet this still leaves enough of a gap to negotiate most kerbs, road humps etc. without worry.
The seat has four or five settings for 'reclinement' of which this demo was set quite low (although not at the lowest) - David offered to set it up less extreme, but I thought I should try to embrace the beast...
And it is a beast! To get my recumbent 'eye' in, I rode David's Nazca Fuego for a couple of hundred yards, then I was ready to go low... (the Fuego is a high bike in comparison) For reference I was able to comfortably balance the bike with one palm on the ground, and my arms are not particularly long! Easy to ride
To my amazement I didn't really find the RaptoBike any harder to start, or drive, than the other recumbents I had tried. It took me a few minutes to relax but once I trusted that the bike could really be this
stable, it purred along quite contentedly. I carved a few gentle turns and negotiated some joggers and upright riders with no drama at all!
My only upset occurred when waiting to cross at a red light... I was hand-standing (because let's face it, if you can, you will!) and I tried to ride off while still bearing weight on the hand - clearly a non-starter! I had to dab my foot down and re-cock the pedals before hurriedly moving off past the light As comfortable as a armchair
The seat and headrest (not fitted as stock) were extremely comfortable. In fact I thought if you had a kickstand and brought some beer you could easily fall asleep while clipped into the Rapto... try that on my other bike!
The handlebars on the RaptoBike are very strange. Basically they are shaped like an arrowhead, so when gripping the bars your thumbs are up towards your face and your pinkies down towards your feet. However in the riding position, this keeps your wrists absolutely neutral and felt very natural. Maybe a lot of low-racers have this but it is a masterpiece of ergonomics...
Although the frame is rigid the ride quality was very fine, with 40mm (1.5") Marathon tyres fitted. This says a lot as Marathons are my all time least-favourite tyre! (We didn't ride really bad surfaces though, it was all paved OK with reasonably lowered kerbs so take this with a pinch of salt). David said he could fit down to about 28mm tyres but of course you can't unweight the bike as on an upright, so for my kerb dodging, pothole bashing adventures wide may be more sensible!Frisky performance
Remember I didn't have the skill / confidence to really sprint the bike in a big gear, or do any of the aggressive jinks and dives that you use to negotiate snarled up streets... but for what it's worth, the frame and wheels were solid and undisturbed by the power I was managing to lay down.
My upright bike weighs about 17lbs fully kitted out. I was prepared for the fact that the RaptoBike, for all its aerodynamic advantage, might be quite a lot more sluggish at 30lbs stock. In fact, I could hardly believe how light and responsive the bike felt - more like it weighed 20lbs than 30 I must say.
We zipped along the cycle path and even climbing a couple of shallow hills, speed was completely limited by my courage and not the bike (although I have no recumbent legs, it drives very well indeed!) I would say that maybe we took it to 15-20mph and it was very steady and confident when I remembered to release my death grip on the bars!
I was able to effortlessly do a 'U turn' by standing up from the seat, lifting the bike by the tiller and turning around - the weight distribution is quite even as the length of the bike seems balanced by the front driving wheel. Another thing you can't easy do on a normal bike...Starting and stopping
The RaptoBike comes with nice, if not overly sporty finishing kit - it's all brand name stuff from Avid and SRAM without any dodgy generics to be seen.
The gearing of 1x8 speed would be perfect if you don't need to climb steep hills. As it is I was not completely convinced because the fixed-wheel has made me a spinner and even the lowest gear is not dramatically low (maybe in the mid 30's) - of course, I have no recumbent legs to compare!
David had ridden the bike up the Hawes Brae at South Queensferry (which is about 7% avg I think?) so clearly a regular rider can get by OK.
You can fit a double up front via an attachment on the boom (which will also be the perfect place for lights) if you so desired. There are stops etc. brazed-on to manage the front dérailleur cable. For me I think the simplicity would be spoiled and I may just order with a slightly smaller chainring or a different cassette (especially as I want 155mm cranks).
The bike comes with V-brakes which are light and simple and doing an OK job. I think maybe I would like a front disc though, to compensate for the bike's speed on all-weather commutes - of course that's not an option on a lightweight upright road bike (another advantage to the recumbent)..Front wheel drive
I feel like I should be able to make some comment on the fact that the Rapto is front wheel drive. But to be honest, I didn't notice anything to remark on - I followed David through corners without noticing anything from the chain, and I didn't get wheelspin or anything funny going on (not that we were climbing steeply), or any interference with the steering.
I think if you want to squeeze down the side of a bus and do a 90 degree left turn next to the kerb, you might struggle with such a tight radius. But if you are riding 'normally' I can't imagine having many FWD-related problems.Final thoughts
If I could have ridden home on it, I would have! The RaptoBike really is a fine piece of kit and it is crazily cheap (for a recumbent) considering what it can do. The fact that a total novice could ride it around for an hour without any issues I think has to speak highly of the handling.
It is funny being so low compared with an upright, but if I am honest I think you either can see over the cars, or you can't. And if you can't, even a foot of height difference will not be too relevant in safety terms.
One startling thing was how excellent the mirror on the RaptoBike was; it didn't shake and offered a completely clear, wide-angle view without any body parts or bike parts to be seen. Almost as good as our car mirrors - I think it will be hard to force myself to shoulder check with one of these!
Oh, and it felt just the same going at 15mph as at 5mph - like it was a bit bored and wanted to let some of the beast out!
I am in David's debt for giving up two hours of his time on a damp, cold, and windy evening to risk his nice low-racer on a beginner... if you are anywhere near Edinburgh and vaguely interested in recumbents then he is the man to speak to (here
