Power delivery is smooth, and quite adequate for most tasks. I'm sure folks smaller than me will find it very spritely. It's not too hard to work this out, but still The claims that the frame will suit people up to 6'4" may be a little optimistic. I'm 5'11", and to get into the optimum pedal position I need the seat post up very high, almost to feet completely off the ground level, chiefly because the frame places the seat relatively far forward over the pedals, so potential buyers should try this out to be sure.
Shorties may find this a plus point. Now the real stuff Why are the levers attached to the brakes by bungee cord? Surely a couple of quid extra on decent cables could be spent. Levers go straight back to the bars with minimal pressure as soon as you use them, and cannot be tightened without the brakes binding on the wheel.
Went straight out and bought some decent shimano cable and housing and replaced mine - make sure you do the same. Similarly I binned the vexatious promax disc at the front, and V brake at the rear and replaced them with an Avid BB07 disc, and Avid single digit V brake at the back.
A big improvement, but if nothing else - do those cables!! I stress this as a result of my previous experiences on my old bike on steep downhills - see my introductory posting for details. The hill climbing ability is fine if the hills are not over about , but lacking above this even compared with my previous heavy old powabyke 24spd.
Basically this is because the standard bike is over geared. This however can be addressed. I replaced the Shimano 14tt megarange hub with an 11tt one, also replacing the 52t front sprocket with a 42t one and reducing the chain length correspondingly fit the chainring inside the crankset not on the outside, as due to the chain path it will constantly fall off in the low gears otherwise. This makes a terrific difference. The bike now has a slightly higher top gear and can actually go faster on flat or downhill, but all the other 6 gears get progressively lower than their predecessors.
Please take note Wisper - why not consider doing this on future models? Lastly, its a pity that you have to remove the seat post to take the battery out unless you have the optional tilt seat but this is not a major problem. This is a great bike as standard.
The perfect bike for everyone doesn't exist. I like to give a constructively critical review however, and some of the imperfections listed can be easily and cheaply remedied.
If you do this you can turn a basically very good bike into a great one. I liked the bike when it arrived. I love it now. High capacity battery. Most components of decent quality. Rides nicely. Handles nicely. Quick recharging, with a good quality charger. Mainly due to poor quality very stretchy cables. I found it overgeared for my area very hilly , but I'm a pretty heavy chap - about 15st , so that may not apply to everyone else.
Seat very uncomfortable, but again may be down to personal preference. Supplied with headset bearings not properly tightened, and same for crankset. Where's the manual? I really look forward to my daily commute on it. It is growing on me more and more as time goes by. The 'off road' speed boost option is really useful at times when you want to crack on into a headwind on the flat.
Unfortunately this setting does not apply to the pedelec mode which I mainly use - I always pedal assist even in throttle mode. This is such a shame, if it could be wired to allow the motor to contine to assist up to 19mph in pedelec mode it would be great. I found the brake cables very stretchy, and had to replace those. The braking improvement was dramatic. I improved this further by replacing the promax front disc with an Avid BB07 they're the business!
This gives me a slightly higher top gear, as well as some much better low ratios on the steep stuff in other words a wider range of gear ratios than standard. The seat had to go, but then I've never bought a bike yet that couldn't be considerably improved by changing the saddle, and this again is down to personal preference. The bottom line, if the bike was nicked, would I replace it with the same model? At the moment the answer has to be yes, definitely.
This is a bike that grows on you, the more you use it the better it gets. You could do much worse! With proper brake cables 9. How about it you chaps Wisper? AndyB Finding my electric wheels. May 8, 17 0 Loughborough. Wisper se First Impressions Whilst I was considering buying an electric bike I found this website enormously helpful, so having just purchased a nearly new Wisper SE I thought it might be useful to give some first impressions.
I bought a second-hand just over a month ago, it was nearly new with some improvements made by previous owner. I purchased the bike with a view to commuting to work, 11 miles away with small hills, maximum climb of 35m, an overall climb of 30m from work to home. I often have to carry my laptop home. My aim was to get a little fitter, but not arrive at work too exhausted, and, as my job is looking at low carbon technologies, to practice what I preach by reducing my carbon footprint.
My negatives below are really just niggles rather than serious problems. Appearance: I like its looks very much. Competition: As I live near 50 Cycles in Loughborough I took an Agattu out for a test run up the highest hill on my journey to work. Controls: Probably the most disappointing area.
The biggest issue is there is no indication of which mode I was in or what to press to get to another mode. On my initial trips out it took a lot of experimenting to work out if the switches toggle or needed holding continuously. The instruction manual was pretty poor too, in fact it said nothing about the controls. Therefore I tend to always use the bike in derestricted throttle mode as it makes me feel in control.
Display: The speedo is pretty useless only displays when power is applied, is very granular, is in kmh and is a bit dim. The battery indicator goes from empty to full, but actually seems to just indicate battery voltage. So under load, eg up a hill, the display lights drop but recover when the throttle is released. It still has value but something better that told you what was really left in the battery would be more useful.
Lights: A bit naff and tyre driven dynamo is quite a drag. Previous owner had added extras which is probably necessary for night cycling. This is the main reason for buying it and it delivers well here. Battery: It has sufficient range for my 22 mile commute. I have an adapter that measure wattage so have found that most of the charging is done in the first 2 hours, after that it is a little trickle. Gearing: A little low, I may address this with a bigger front sprocket if possible.
Now those of you living in hilly terrain may disagree with this so I think the real problem is the lack of range from top to bottom, I notice another reviewer has had to address this. Brakes: Previous owner had sensibly changed these so no complaints.
Looks: Very smart. Frame: A nice sturdy frame. Support: Not had to call upon this but found the answer to my question about warrantee validity a bit disappointing, looking for lots of wriggle room, whereas I think warrantee should automatically transfer with no problems. This accelerates depreciation a little. Very quite motor and smooth power delivery. Comfortable ride, good range of gears coupled with "solid" relable gear changes.
Brakes are adaquate. Off road function is excellent for the few extra MPH it provides. Rides well without electric assistance. Weaknesses: Frame warranty of only two years. Bottom bracket bearings failed and had to be replaced. Summary: Its fun to ride and a talking point. Even seasoned non-assist cyclists like the design and had fun riding the Wisper.
Good support from the chaps in Cambridge - no hesitation recommending them along with the Wisperse. Most enjoyable part - overtaking other cyclists and leaving them behind for the same amount of effort! Overall Rating: 9. Aug 9, 0. This was the main reason for me choosing the Wisper. It's quite a heavy bike and so I feel uncomfortable when riding rough trails.
It feels like I could quite easily break something if I hit a rock at a bad angle. I reckon rear suspension is necessary for a bike of this weight when riding off-road. But then rear suspension would slow the bike down on tarmac. To be fair, this probably applies to all electric bikes. So please don't take this as a criticism against the Wisper.
The brakes are quite poor, but once again, I believe this is partly because of the weight of the bike. There are 2 different batteries available for this bike, the 8A battery is the most freindly on the wallet. Our company has been built on an underpinning knowledge of the use and quality of different electric bikes brought about from staff with years of experience previously working within the bike industry.

Everything about the bike exudes quality. The frame and welding detail, the suspension, gears and power — and everything still works faultlessly 1 full year after purchase Smile Bikes Norfolk — Thank you so much Tim for test rides and support. Bike journeys are now a joy and my wife who is relatively new to cycling actually looks forward to her commute! So the suits the novice as well. I am an experienced but unfit cyclist and have taken this bike all over Norfolk on and off road. Suspension and range are particularly impressive — we have the Torque Power Back and Wh The pleasure we have got from this bike is just immense.
