Recommend the company and the product
This product is great, and the customer service experience was also great. So good, in fact, that I felt the need to review it, which I almost never do (ain't nobody got time fo dat).
The kit is fairly straightforward to fit thanks to the surprisingly comprehensive set of tools that it comes with. Once fitted, it does what it says in the advertising. I've had it on for a couple of months, and done 1000km or so.
RANGE I'm getting about 60km out of a battery charge on 50% assist on the flat, on quite a heavy bike with a 80+kg rider.
BATTERY The best thing about this kit that it has over other similar products is the very elegant battery management technology. Smart gyros and an adjustable top assist speed mean the motor (and therefore battery) only work when they are needed. This greatly improves range per charge, meaning the relatively small battery is capable of big things, and only takes a few hours to charge from empty.
POWER: Uphill performance is also good, with just enough power to take the edge off on *really* steep hills but still need some input from the rider (which is what I want, rather than a motorcycle). For gradual inclines, little to no effort is needed from the rider.
Power application is nice and smooth too, picking up at 6kph and pushing steadily until the top speed is reached. The variable top speed influences battery life, so if you're happy to ride a little slower, you'll go farther (23kph seems to be a sweet spot for me - it's good if you can cut the power near your natural cruising speed).
MODES: I also appreciate the 'climbing' mode, which just functions as a normal bike until the gyro detects a hill, then kicks the motor in for assist. Great for full-day rides where some fitness is the goal. You can always kick into manual mode or up a notch when you start to flag. Being frugal with the assist or using climbing mode, a full day ride on a single battery charge is absolutely doable...at 100% assist into the wind or on a hill, without effort from the rider, an hour of powered riding is more realistic. I find this absolutely suits my needs, as I want to work together with the bike rather than be completely carried by it.
CUSTOMER SERVICE: I'd like to say thanks to Jamie from Ultra, who responded promptly throughout the order process, answering questions reliably and knowledgeably, and taking care to make sure things ran as expected. I'd be confident of reliable help if needed at some point in the future.
The all important question is: if it was stolen, would I buy the kit again? The answer to that is a definite yes. It has changed the way I view cycling and made it a realistic alternative to a car for my purposes.
