How to choose a Child's Bike

In contrast to many children's bikes, Frog bikes are sized by the length rather than age, as this is the most reliable way of getting the right size of bike for each child. Age alone isn't a reliable measure as there is a large spread of "normal" leg lengths & heights for age.

Please take the time to measure the rider's inside leg. It's easy to measure:

  1. Stand the child in socks against wall
  2. Place a small book between their legs, as high as is comfortable
  3. Ask the child to move away and measure from the top of the book to the floor

Once you have measured the inside leg, use this table to find the right size bike for your child. Note we give the MINIMUM inside leg length for each bike, with the saddle at it's lowest setting. At this height, the child will safely be able to get their feet to the ground. Don't worry - Frog Bikes have long seat posts, so the saddle can be raised a long way as the rider grows.

Of course all children have different length arms and torsos too, so to ensure a comfortable riding position, the handlebar height can be tailored, and saddles can be slid back and forwards on their rails.(These adjustments are easy to do and just need an allen key; instructions are in the manual that comes with each bike.

Bought for my 9 year old son who loves the Team Sky version. The aluminium frame means it is much lighter than his previous smaller steel framed bike - you appreciate the difference when you have to pick it up to put it away after him! It is also the new 8 speed model rather than the older 7 speed as stated on the spec. Not the cheapest kids bike but highly recommended in terms of quality.
This bike is perfect. Every thing is is in right size. The weight, q-factor, crank length, handlebar back sweep, brake levers and so on. After unpacking the bike, I needed to adjust each brake shoes a bit but others were in fine conditions.
I'd like to give it 4.5 rather than 5 because I can always find something to improve upon, but Merlin does do do half stars and 4 is too low. I'm in Canada so we have a lot of choices for bikes this size, however most come with a shock on the front. And frankly, I think a shock is so stupid, unless your kid truly is killing it on trails and the shock is good enough to actually work for a ~60lb kid. So basically anything in this price range with a shock is nothing more than a boat anchor bolted to an 8 year old's bike. Awesome. The other thing so many kids bikes have that are idiotic is multiple front chain rings. For the type of riding 8 to 10 year olds commonly do, a single ring matched with a cassette where some thought has been put into the gear range is more than adequate. It's simpler. It's lighter. And come on, even adult bikes are getting tough to find with a triple, let alone a double. There are a few Islabikes floating around where I live, but very few, They are very expensive and must be purchased out of the US. The US part is not a big deal but the price tag is. The Frog 62 is $407CAD and shipping was free. The Beinn 24 is $780CAD and $52 to ship to a US location. I'd have to assume double that shipping price to Canada. Prior to making my purchase I noticed a review here stating the cranks were 127mm on the bike the reviewer received. This would mean it was a '16 model and not the '15 as Merlin's current description (as of July 2016) advised. I contacted Merlin to confirm and they did get back to me promptly saying the bikes were all '16's. So I was sold. The 127mm cranks (rather than the 140's on the '15) + a 32 tooth front ring (rather than a 36 on the '15) + an 8 speed 12/32 cassette (rather than the 7 speed 14/28 cassette on the '15) = a far better spec'd bike for it's target rider than the '15 model. I don't know if the '15 came with the two sets of tires, but it's a nice bonus. I don't know if I'll use the slightly wider knobbies but nice to have them in case a lot of trail riding is in my daughter's future but I don't see it. It comes with a pack of reflectors and matching ('s so made-in-China) touch up paint. It comes with a pack of clear adhesive patches to put over wear areas like chainstay (although comes stock with one on the chainstay already) and circular ones for cable rub areas. Although I cannot see myself putting them on (since my kid probably won't be out riding around in the rain) it comes with a set of fenders. I'd rather see the strut style like are commonly put on adult commuter bikes etc rather than these big plastic flaps. I'm sure they do an adequate job, they just look terrible. I think the bike should come with a marginally wider handlebar. My kid had an Opus Nix 20" bike before, which is very similar to the Frog, and even that had a wider bar...I'm thinking it was about 40mm wider. The ones on the Frog seem exceptionally narrow. Doesn't matter, my daughter will get used to them. The seatpost is pretty bad. Yeah, it's a kids bike, and it's a relatively inexpensive bike for what you get (actually, it's a downright bargain). I am not a fan of set back posts on anything I ride and that spills over to my child's bike. There is too much set back for an 8 year old and because the saddle rails are small and slightly curved it is impossible to mount the saddle and level it anywhere but middle of the rails. So she's got a cool old school Syncros post out of my parts bin on there now so she's about 2" further forward than with the stock post. The only other niggle I have is the cables/housing are left way too long. If your kid is throwing truck drivers and bar spins the no worries, but mine is more into kickstands and ensuring it has a bell so having enough cable to allow the bars to fully rotate more than 360 degrees is of no benefit and it looks sloppy. It does not take long to trim them but I don't know what the point of all that extra cable out front is. The two green spokes, one each side of the valve is cool and they match the few little green frog graphics on the bike. Subtle but cool touch. So I'm in Canada as I said. I ordered with the free shipping option. It took the bike exactly 6 business days to get here. It shipped through something called "Spring Parcel". I thought the tracking was good and timely and whoever the carrier is hands off to Canada Post. I had no further fees outside of the purchase price. I know this is hit or miss in Canada, but with Merlin I seem to always get away with no taxes or import charges even on pricier orders.
My daughter`s inseam is 58cm. By lowering to the bottom of the saddle, it was possible to ride. The body is very light, comfortable, maneuverability even in children. Since the spare tire and the tube had come with it, it is good. Crank set was not 140mm. It was 127mm. I am very happy.
Great service, prompt delivery and a fantastic looking bike. My son is delighted and his friend's were jealous on his birthday. What more can a 9 year old ask. Highly recommended.
